Answer:
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
