Davin Harris · Answer 1

78.375 miles per hour = R

Step-by-step 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

Caroline Mcintyre · Answer 2

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.
