Question

Claire power walks 1/9 of a mile in 1/54 of an hour compute the unit rate as the complex fraction

Answer 1

1/9 * 54/1 = 54/9.

So she is walking 6mph.

Answer 2

`(54)/(9)\text{ miles per hour}`

Explanation:

Unit rate is the units of first quantity in one unit of second quantity.

Given,

Number of miles walked =
`(1)/(9)`,

Number of hours =
`(1)/(54)`

Thus, the unit rate

`=\frac{\text{Number of miles walked}}{\text{Number of hours}}`

`=(1/9)/(1/54)`

`=(54)/(9)`

= 6 miles per hour
