Answer:
1/3 minute and 1/2 minute (2 different problems)
Explanation:
If 3/4 miles are covered in 6 minutes, then the relevant unit rates here are:
3/4 mile
---------------- = 9/2 mile/minute, or
6 minutes
6 minutes
---------------- = 8 minutes/mile
3/4 mile
If we know that the distance covered was 1 1/2 miles, we divide that by (9/2) mile/minute to determine the elapsed time:
3/2 mile
--------------------- = 1/3 minute
(9/2) mile/min
If the dist. covered was 2 1/4 mi, dividing that by (9/2)(mile/minute results in:
9/4 mi
------------------- = 1/2 minute
9/2 mile/min
