Question

Your family is driving to Disney which is 1000 miles away. The first day yourfamily drives 600 miles in 10 hours and the second day they drive the remainingdistance in 8 hours. What is the average speed of travel for the second day?

Answer 1

We know that the average speed is defined as the distance traveled over time, that means that the average spees is:

$v=\frac{d}{t}$

Now, since the family drove 600 miles the first day this means that the second day they drove 400 miles and that they traveled that distance in 8 hours, this means that the average speed the second day is:

$\begin{gathered} v=\frac{400}{8} \\ v=50 \end{gathered}$

Therefore the speed was 50 mph the second day.
