To calculate the reasonable speed for the car to travel, we need to know the distance between the starting point and the destination. Assuming the distance is around 400 miles, a reasonable speed would be around 50 mph, which is a typical speed limit on many highways in the US.
I picked this number because it would ensure safe travel, as well as provide ample time for rest stops and possible traffic congestion. Also, maintaining a constant speed for most of the trip helps reduce fuel consumption and prevent premature wear and tear on the car.
Your family decides to take a long road trip for the summer. You will be riding in the car while it moves at a fairly constant rate for eight hours to reach your destination.
What do you think is a reasonable speed for the car to travel at for most of the trip? Remember to include units of measurement in your answer.
