6. It took Juan 48 minutes to drive 12 miles, Calculate his speed in miles per hour,

15 miles per hour

Step-by-step explanation:

First, lets find the number of miles he goes in 1 minutes.

That would be found by dividing the number of miles (12) by the number of minutes (48), so we have:

12/48 = 0.25 miles per minute

We want the speed in miles PER HOUR.

So, how many minutes are in an hour?

That is 60 mins = 1 hr

So, we need to multiply this by 60. So,

0.25 miles per minute * 60 minutes (1 hr) = 15 miles per hour
