Question

A cyclist rode 3.5 miles in 0 4 hours1. She was goingmiles per hour2. At that rate, it will take herhours to go 5 miles,

Answer 1

To find the unit rate, we just have to divide

`v=(3.5mi)/(0.4hr)=8.75mi/hr`

She was going at 8.75 miles per hour.

Then, we use this rate to find the time needed to travel 5 miles.

`(5mi)/(8.75mi/hr)=0.57hr`

It will take 0.57 hours to go 5 miles.
