What time is 80 minutes before 1:10

11:50

Step-by-step explanation:

1:10-10 minutes = 1:00

1:00-60 minutes=12:00

10+60=70

80-70=10

12:00-10 minutes = 11:50

11:50

Step-by-step explanation:

Since there are 60 minutes in an hour, and 80 = 60 + 20, go back one hour from 1:10 and then subtract 20.

1:10 - one hour = 12:10

12:10 - 20 minutes = 11:50
