Choice B

Step-by-step explanation:

A 1 hour = 60 minutes

  2 hours = 120 minutes    

Choice A is False

B 1 day = 24 hours

2 days = 48 hours

1 hours = 60 minutes

2 hours = 120 minutes

Choice B is true

C 1 day = 24 hours

1 hour = 60 minutes

False

D 1 minute = 60 seconds

1 day = 24 hours

False

B. 2 days is 48 hours, and 2 hours is 120 minutes

Explanation: For every day there are 24 hours.

                     For every hour there are 60 minutes.

                     For every minute there are 60 seconds.

So since there are 2 days, you multiply 24 hours by 2 to get 48 hours. Then since there are 2 hours, you would multiply 60 minutes by 2 again to get 120 minutes.
