Question

Jeremy can row 2/3 of a mile in 1/4 of an hour. What is the unit rate that describes the miles per hour?

Answer 1

2.66 miles and hour, or 2.66/1

Answer 2

Answer:
`2(2)/(3)\text{ miles per hour}`

Explanation:

Jeremy can row
`(2)/(3)` of a mile in
`(1)/(4)` of an hour.

The formula for unit rate (in miles per hour) is given by :-

`\text{Unit rate}=\frac{\text{Distance in miles}}{\text{Time}}\\\\\Rightarrow\ \text{Unit rate}=((2)/(3))/((1)/(4))`

i.e.
`\text{Unit rate}=(2)/(3)*(4)/(1)\\\\=(8)/(3)=2(2)/(3)\text{ miles per hour}`

Hence, the unit rate =
`2(2)/(3)\text{ miles per hour}`
