Answer 2

x represent the Annette's speed on the bike

Explanation:

we know that

The speed is equal to the distance divided by the time

Let

x------> Annette's speed on the bike

In this problem we have

`distance=6.8\ miles`

`time=90\ minutes`

Find the speed

`6.8=x*90`

`x=(6.8)/(90)(miles)/(minutes)= 0.076 (miles)/(minute)`
