Answer:
1) 1 hour
2) 1 hour
3) 2 hours
Step-by-step explanation:
1 hour = 60 minutes
Therefore,
7/8 of an hour implies 7/8 of 60 minutes
7/8 * 60 = 420/8 = 52.5 Mins
52.5 is closest to an hour
5/6 of an hour implies 5/6 of 60 minutes
5/6 * 60 = 50 = 50 Mins
50 is closest to an hour
An hour + Anhour = 2 hours
Total: 2 hours
