Question

Write 171 miles in 3 hours as a unit rate

Answer 1

Speed is distance traveled per unit time

R equals D / T

R equals (171 mi) / (3 hr)

R equals 57 mi/h (mph)

or

171/3 gives MPH

Answer 2

Write 171 miles in 3 hours as a unit rate

Unit rate is nothing but the speed

We know the distance formula

Distance = Speed * Time

`speed = (Distance)/(Time)`

Given distance = 171 miles , Time = 3 hours

`speed = (171 miles)/(3hour)=57(miles)/(hour)`

Unit rate is
`57(miles)/(hour)`
