you are driving to a vacation spot that is 1500 miles away. Including rest stops, it takes you 42 hours to get to the vacation spot. You estimate that you drove at an average speed of 50 miles per hour. How many hours were you not driving?
1500 miles at 50 mph takes 30 hours.
So, there were 12 hours not spent driving.
To find out how many hours you were not driving, you can subtract the time spent driving from the total travel time. In this case, you drove for 42 hours.
To calculate the total travel time, you can divide the total distance traveled by the average speed. You estimated that you drove at an average speed of 50 miles per hour and the vacation spot is 1500 miles away.
Total travel time = Total distance / Average speed
Total travel time = 1500 miles / 50 miles per hour
Total travel time = 30 hours
Now, you can find the time not spent driving by subtracting the time spent driving from the total travel time:
Time not spent driving = Total travel time - Time spent driving
Time not spent driving = 30 hours - 42 hours
Since the result is negative (-12 hours), it indicates that you did not have any rest stops or breaks during the trip.
