Question

You are going to run at a constant speed of 7.5 miles per hour for 45 minutes. You calculate the distance you will run. What mistake did you make in your calculation? [Use the formula S=d/t]

Answer 1

mi/hr • min does not equal mi. you must convert 30 minutes to hours.

Answer 2

mi/hr . min does not equal mi. You must convert 45 minutes to hours.

Explanation:

From the question the speed was given in miles per hour while the time was given in minutes. The time should be converted to hrs before one calculate the speed .

Time = 45 minutes

60 minutes = 1 hr

45 minutes = ?

45/60 = 0.75 hr

Time = 0.75 hr

speed = distance/time

distance = speed × time

distance = 7.5 × 0.75

distance = 5.625 miles
