Answer:

e) 24 miles per hour

Explanation:

Naomi travels 6 miles in 10 minutes

To find the speed, we need to divide DISTANCE by TIME

However, to do that, we need to change the 10 minutes into hours.

10 minutes = 1/6 of an hour

Now, 6/ 1/6 = 36 miles per hour

_________________________

Maya travels 12 miles in 30 minutes

To find the speed, we need to divide DISTANCE by TIME

However, to do that, we need to change the 30 minutes into hours.

30 minutes = 1/2 of an hour

Now, 6/ 1/2 = 12 miles per hour

_________________________

36 mph - 12 mph = 24 mph
