Question

Kristin jogs around a park that has a perimeter of 1/2 mile. Kristin jogged around the park 4 times in 50 minutes.What is the unit rate of Kristin's speed?

Answer 1

First, find the total of the distance she went through
distance = 4 × the perimeter
distance = 4 × 1/2
distance = 2
The total of the distance is 2 miles

Second, calculate the speed
speed = distance/time
speed = 2/50
speed = 4/100
speed = 0.04 miles/minute

Kristin's speed is 0.04 miles/minute
