Ava and kelly ran a road race, starting from the same place at the same time. ava ran at an average speed of 6 miles per hour. kelly ran at an average speed of 8 miles per hour.

when will ava and kelly be 3/4 mile apart?

The answer is:

It will took 0.375 hours for Ava and Kelly to be 3/4 miles apart.

To calculate how long after they start they will be 3/4 miles apart, we need to write two equations.

So, writing the equations, we have:

Calculations for Ava:

We have the following information,

Then, writing the equation,

Calculations for Kelly:

We have the following information,

We need to calculate when Kelly will be 3/4 miles apart of Ava, so, it's position will be the Ava's position plus 3/4 miles.

Then, writing the equation,

Now, substituting Ava's speed into the second equation, we have:

Hence, we have that it will took 0.375 hours for Ava and Kelly to be 3/4 miles apart.

Have a nice day!
