Answer:
44 minutes
Explanation:
Given:
Michelle started doing a puzzle at 7:50 p.m. She finished the puzzle at 8:34 p.m.
To Find:
How long did Michelle work on the puzzle?
Solve:
Began Time ⇒ 7:50 p.m
End Time ⇒ 8: 34 p.m
Since they are both p.m we could just subtract 8:34 by 7:50.
But first we know that:
8: 34 the 34 can't be subtracted by 7:50 the 50.
Thus we know that:
1 Hour = 60 minutes
Hence,
changing 8:34 p.m from 1 hour to 60 minutes. Which given us 7:94.
Then,
7:94 - 7:50
= 44
Hence, Michelle work on the puzzle for 44 minutes.
