You are driving to a vacation spot that is 1500 miles away. Including rest stops it’s takes you 42 hours to get to the vacation
Serga [27]

You were not driving for 12 hours.

<em><u>Explanation</u></em>

Distance to the vacation spot is 1500 miles and you estimate that you drove an average speed of 50 mph.

<u>Relationship between distance, speed and time</u> is.......

distance=speed*time\\ \\ time=\frac{distance}{speed}

So, the <u>number of hours you drove</u> =\frac{1500}{50}hours= 30 hours

Given that, including rest stops it’s takes you 42 hours to get to the vacation spot.

Thus, the number of hours you were not driving =(42-30)=12 hours
