Samuel spent 2 7/12 hours studying in the morning and 1 7/8 hours in the evening. How much longer did Samuel study in the morning?

42.5 minutes

Step-by-step explanation:

7/12 of an hour equals 35 minutes, so

2 7/12 hours = 60 + 60 + 35 = 155 minutes

7/8 of an hour equals 52.5 minutes, so

1 7/8 hours = 60 + 52.5 = 112.5 minutes

155 - 112.5 = 42.5 minutes

Samuel spent 42.5 more minutes studying in the morning. *I don’t know if your answer is supposed to be rounded up, if so it would be 43 minutes.

I hope this helps!
