$60\textup{ mph}$

$65\textup{ mph}$

$6\textup{ mph}$

$34\textup{ mph}$

Explanation

To answer this question, we need to recall the formula for speed:

$\textup{speed}=\frac{\textup{distance}}{\textup{time}}$

We can plug in the known values from the question to solve:

$\textup{speed}=\frac{600\textup{ miles}}{10\textup{ hours}}$

$\textup{speed}=60\textup{ mph}$
