The unit rate is D.

Answer 2

D.60.86 miles/hour

Explanation:

This can be solve as a rule of three problem.

We have that the person traveled 426 miles in 7 hours. Each option is in miles/hour, so the problem asks you how many miles the person traveled in 1 hour. So

426 miles - 7 hours

x miles - 1 hour

`7x = 426`

`x = (426)/(7)`

`x = 60.86`

So the correct answer is:

D.60.86 miles/hour
