Question

Jeremy can row 1/3 of a mile in 1/4 of an hour. What is the unit rate?

Answer 1

`Rate=(distance)/(time)\\((1)/(3)mile)/((1)/(4)hour)=(1)/(3)*((1)/(4))^(-1)\\ (1)/(3)*(4)/(1)=(4)/(3)=1.333333...`
So Jeremy can row 1.333 miles per hour.

Answer 2

The unit rate that Jeremy can row is 1.33 miles per hour.

Explanation:

Unit rate is defined as the distance over a time period. The distance that Jeremy can row is given and the time period is given.

The distance (miles)
`=1/3=0.33`

The time period (hours)
`=1/4=0.25`

The unit rate is distance per time:

`=0.33/0.25=1.33`

The unit rate that Jeremy can row is 1.33 miles per hour.
