Answer 1

Answer:

Johnny and his family left home at 10:00.

Step-by-step explanation:

First, You add all of the minutes up,  

45+20+10= 75

Then convert the minutes to hours,  

75 mins = 1 hr and 15 mins.

Add the hours together,

1 hr + 2 hrs = 3 hrs

Then add minutes,

3 hrs and 15 minutes

Subtract 3 hrs and 15 mins from 13:15,

13.15 - 3.15 = 10:00

Your answer is:  

Johnny and his family left home at 10:00.
