You're answer is B: 78.375 my reasoning is because you have the time and the diatance. Divide the distance by the time and you should get the miles per hour.

Answer 2

78.375 miles per hour = R

Explanation:

D= RT

The miles are 313.5 which is D and the time is 4 hours

313.5 = R * 4

Divide each side by 4

313.5/4 = R

78.375 miles per hour = R
