Question

What's the unit rate if Marcus walks 9 miles in 3 hours.

Answer 1

Explanation:

find average velocity with knowns of displacement and change in time.

formula : v = x/t

v = average velocity

x = displacement

f = change in time

Given

t = 3 hr

x = 9 mi

9/3 = v

v = 3 mi/h

Answer 2

The unit rate is:

⇨ 3 mph

Work/explanation:

To find the unit rate, we divide the distance (9 miles) by the time (3 hours):

`\sf{Unit\:rate=(distance)/(time)}`

`\sf{Unit\:rate=(9)/(3)}`

`\sf{Unit\:rate=3\:mph}`

Hence, the answer is 3 mph.
