Answer:
Haeather ran at a speed of 5 miles per hour.
Step-by-step explanation:
Given that last week at the park Haeather ran 4 miles in 48 minutes, to determine what was Haeather rate of speed in miles per hour the following mathematical calculation must be performed:

60/12 = 5
1 x 5 = 5
Therefore, Haeather ran at a speed of 5 miles per hour.
