Answer:

hi there!

the correct answer is:  one hour and 4 mins

Step-by-step explanation:

well first of all you want to convert 7 3/5 hours to minutes which you will get 456 minutes

then you want to subtract 72 mins (30+42) from 456 and you get 384

then since there are 6 classes a day, you will divide 384 by 6 to get 64 so each class is one hour and 4 mins

Answer:

1 1/15 hours each class

Step-by-step explanation :

I'm pretty sure this is the answer and here is why :

7 3/5 = 456 in minutes

30  + 42 = 72

384 divided by 60 = 6.4

and

6.4 divided 6 = 1. 066666667 so the answer choices :

1 1/15 hr - 1 3/20 - 1 11/60 - 1 4/15

There would only be one correct answer and it is 1 1/15 here's why :

We get that the one stands for hours but 1 divided by 15 equals = 0.066666667 and it matches our answer from before.
