Johnny and his family arrived in Williamsburg Virginia at 1:15 p. m. they drove for 45 minutes after they stopped for lunch their lunch break was 20 minutes they drove for 2 hours and 10 minutes before stopping for lunch what time did they leave home?

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.
