Question

Find each unit rate.
Rachel drives 180 miles in 3 hours ​

Answer 1

60 mph.

Explanation:

Remember Newton's 2nd law of motion.

`a = (v - u)/(t)`

We are not on acceleration though. We are on how fast he is going. (U).

Rachel drives 180 miles in 3 hours.

v ÷ t

= 180 ÷ 3

= u

= 60 mph.

Rachel is driving 60 mph.

hope this helps.
