Question

Katie ran 4 miles at a rate of 1.1 miles slower than jasmine hiw many minutes did katie run if jasmine ran 5 miles at 8.4 minutes per mile

Answer 1

Katie spent 29.2 minutes

Explanation:

Given

Jasmine:

`Distance = 5\ miles`

`Rate = 8.4\ mins/mile`

Katie:

`Distance = 4\ miles`

Rate = 1.1 mins/mile slower than Jasmine

Time spent by Jasmine:

`Time = Distance * Rate`

`Time = 5\ miles* 8.4mins/mile`

`Time = 5* 8.4mins`

`Time = 42\ mins`

Time spent by Katie:

`Time = Distance * Rate`

We have that:

Rate = 1.1 mins/mile slower than Jasmine

So,

`Rate = 8.4 - 1.1`

`Rate = 7.3`

`Time = 4 * 7.3`

`Time = 29.2 \ mins`
