Answer:
Jerry needs to study for 1 hour to reach his goal.
Step-by-step explanation:
Monday
1 1/2 = 1 hour, 30 minutes
Tuesday
2/3 of an hour
1 hour = 60 minutes
60 / 3 = 20
2/3 of 60 = 40 minutes
Wednesday
5/6 of an hour
1 hour = 60 minutes
60 / 6 = 10
5/6 of 60 = 50 minutes
How much time he has studied already
1 hour = 60
60 + 30 + 40 + 50 = 180
180 / 60 = 3 hours
How much more time does he need to study
4 - 3 = 1
Jerry needs to study for one more hour.
