Question

Can you plz help me in number 6 part a and b explain how you did it plz and plz answer by 5th grade level thx

Answer 1

Part A: 1 hour and 45 minutes.

Part B: 10:10 P.M.

Explanation:

Part A

We know that 1 hour has 60 minutes.

Then from 7:00 P.M to 8:00 P.M there are 60 minutes.

If 7:35 P.M. is 7 hours and 35 minutes, then the amount of minutes left for 8:00 P.M. is:

`60minutes-35minutes=25minutes`

From 8:00 P.M. to 9:00 P.M there is 1 hour.

And from 9:00 P.M to 9:20 P.M. there are 20 minutes.

Then you have 1 hour and:

`25minutes+20minutes=45minutes`

Therefore, How long was the movie?

1 hour and 45 minutes.

Part B

Knowing that Ushma got home 50 minutes after the movie ended, you need to add 50 minutes to 9:20 P.M:

The amount of minutes left to 10:00 P.M. is:

`60minutes-20minutes=40minutes`

So, here we have 40 minutes of the 50 minutes she took to got home.

The remaining minutes were:

`50minutes-40minutes=10minutes`

Then, when 40 minutes passed, the time was 10:00 P.M.

And when you add 10 minutes to 10:00 P.M., you get the time: 10:10 P.M.

Therefore:

Ushma got home at 10:10 P.M.
