Question

On a bicycle, Sarah rides for 6 hours and is 44 miles from her house.After riding for 12 hours, she is 86 miles away.What is Sarah's rate?

Answer 1

To determine the Sarah's cycling rate, here are the steps:

1. Subtract 44 miles from 86 miles.

`86mi-44mi=42mi`

2. Subtract 6 hours from 12 hours.

`12hrs.-6hrs.=6hrs\text{ }`

3. Divide the result in step 1 by the result in step 2.

`42mi/6hrs=(7mi)/(hr)`

Hence, Sarah's cycling rate is 7 miles per hour.
