Answer:
CJ ran at a rate of 7.5 miles per hour.
Explanation:
CJ ran 6 miles in 48 minutes. To know his rate in miles per hour, we have to do the following calculation:
48/6 = time spent to run a mile
CJ run a mile every 8 minutes.
60/8 = miles CJ was able to run in an hour, therefore, his rate in miles per hour.
60/8 = 7.5
According to this calculation, CJ ran at a rate of 7.5 miles per hour.
