Question

Julia rides her bike at a rate of 1/2 mile per 1/9 of an hour. how far does she ride in one hour

Answer 1

4.5 miles

Explanation:

0.5 of a mile per 1/9 of an hour.

rate x time=distance and you need to find distance for one hour not 1/9 so multiply it by 9 so

0.5*9=4.5, 1/9*9=1

rate time distance

4.5 * 1 = d

4.5*1=d

4.5=d

so the distance traveled in one hour is 4.5 miles

Answer 2

4.5 miles

Explanation:

Given:

• Julia rides her bike at a rate of 1/2 mile per 1/9 of an hour.

Let x be the distance Julia rides in one hour.

Create an equivalent ratio of miles to hours:

`\implies (1)/(2):(1)/(9)=x:1`

`\implies ((1)/(2))/((1)/(9))=(x)/(1)`

`\implies (1)/(2)* (9)/(1)}=x`

`\implies (9)/(2)=x`

`\implies x=4.5`

Therefore, Julia rides 4.5 miles in one hour.
