10:45pm-12:15am = 6 3/4 pages How many pages per hour?

Elapsed time is the amount of time that has passed between two events. You can calculate the elapsed time by figuring out the difference between the start and stop time.

Here is an elapsed time problem.

Soccer practice begins at 3:15 p.m. and ends at 4:45 p.m. Determine how long soccer practice lasts.

To solve this problem, set up a subtraction problem that could be used to find the number of hours and minutes that pass between those two times.

Subtract the starting time from the stopping time. Remember that both times represent the number of hours and minutes past noon. 

4:45− 3:15−−−−−−1:30

Soccer practice lasts for 1 hour 30 minutes.

Here is another problem.

A dance performance starts at 7:30 p.m. and ends at 10:10 p.m. How long does the performance last?

Subtract the starting time from the stopping time. 

10:10 −7:30−−−−−−−

You cannot subtract 30 minutes from 10 minutes, so you must rewrite 10:10. Remember, 10:10 stands for 10 hours 10 minutes. Borrow from the hour unit. 1 hour equals 60 minutes. Add 60 minutes to the 10 minutes. 

 109− 7   2   :1070: 30: 40

Events can also occur before noon (a.m.) and end after noon (p.m.). When that happens, finding the elapsed time requires an additional step. This is a result of using a 12-hour clock.

Here is an example.

John goes to school at 8:00 a.m. and returns home at 3:00 p.m. How long was John at school?

You might think that the elapsed time is 5 hours, which would be incorrect. Before finding the difference, add 12 hours to 3:00 p.m. 

12:00 +  1:4013:40

Remember that the day starts at midnight. 8:00 a.m. is 8 hours into the day and 3:00 p.m. is actually 15 hours into the day. Rewrite 3:00 p.m. as 15:00 and find the elapsed time. 

15:00 −  8:007:00

John was at school for 7 hours. 

ExamplesExample 1

Earlier, you were given a problem about James reading his book.

James started at 4:00 p.m. and stopped at 8:30 p.m. Find the elapsed time between the start and end time.

Subtract the start time from the end time. 

 8:30−  4 :00 4:30 

James spent 4 hours 30 minutes reading.

The sharadze family is planning a car trip to atlanta, georgia, which is 279 miles from their home. they plan to drive at an average speed of 62 miles per hour. they also plan to stop for lunch for 45 minutes. based on their plan, when should they leave in order to arrive in atlanta at 3:00 p.m.?

The Sharadaze family should leave at 10:45 am. 

279(miles)/62(miles)=4.5(min.)  4.5(min.)-45(min.)=4.15

10:45+4:15=2:60 which is 3:00

which proves that the Sharadaze family should leave at 10:45 am.

One train traveled south at 60 mph. The other traveled east at 50 mph. How far apart were the trains after 3 hours?

Let's called the train that traveled south train A, and the train that traveled east train B

After 3 hours, train A is 180 miles South
and Train B is 150 miles East

Using Pythagoras, distance between is sqrt(180^2 + 150^2)
30 sqrt(6^2 + 5^2) = 30sqrt(36 + 25) = 30sqrt 61 = 234.307 miles

A student spent 3/4 of an hour reading an article and 2 1/6 hours writing an essay about what he read. how much time did the student spend on the assignment?

So, we need to add 3/4 + 2 1/6.

First, let's find a common denominator.

12 is one.

4 x 3 = 12  3 x 3 = 9        6 x 2 = 12   1 x 2 = 2     2/12 & 9/12 = 11/12

2 + 0 = 2.  2 + 11/12 = 2 11/12.

2 11/12 is your answer.

Ralph is an electrician. He charges an initial fee of $24, plus $33 per hour. If Ralph earned $189 on a job, how long did the job take?

Charge of Ralph:

Charge = $24  + $33 per hour

Let the time worked be = x.

For x hours, the cost = 33*x = 33x

Charge = 24 + 33x

24 + 33x = 189

33x = 189 - 24

33x = 165

x = 165/33

x = 5

The job took 5 hours.

QUESTION POSTED AT 28/03/2020 - 12:04 PM

Your bill from Acme Supply Company is marked "3/15, net 30." The amount of the bill is $178.95. If you pay the bill within 15 days, how much should you tender? A little help please?

Answer:

you should tender $173.58

Step-by-step explanation:

Your bill from Acme Supply Company is marked "3/15, net 30"'

We know When "3/15, net 30" is marked on any bill, it means that if the bill is paid within 15 days there is 3% discount, otherwise net pay within 30 days.

In this question it is asked that if you pay the bill within 15 days, so it is clear that you get the discount of 3% on the bill of $178.95.

Therefore we find the value less than 3% of $178.95.

= 3/100 × 178.95

= 0.03 × 178.95 = 5.3685 rounded to $5.37.

Now subtract 3% amount from the bill amount.

= 178.95 - 5.37 = $173.58

If you pay the bill within 15 days, you should tender $173.58
