Lin ran 2 3/4 miles in 2/5 of an hour. Noah ran 8 2/3 miles in 4/3 of an hour. How long would it take Lin and Noah to run 1 mile at that rate?

We want to see how long it will take for Lin and Noah to run 1 mile. We will see that:

So we know that:

The time in which they run a single mile is given by the quotient between the time and the distance.

For Lin we have:

So Lin runs a mile in (8/55) hours

For Noah we have:

Noah runs 1 mile in (2/13) hours.

Step-by-step explanation:

Given that,

Lin ran 2 3/4 miles in 2/5 of an hour. Noah ran 8 2/3 miles in 4/3 of an hour.

Speed of Lin,

Speed of Noah,

The time taken by Lin to cover 1 mile,

The time taken by Noah to cover 1 mile,

Hence, Lin and Noah takes 0.145 h and 0.1538 h to run 1 mile at that rate.
