QUESTION:
A runner wants to run 10.0 km. She knows that her running pace is 7.5 mi/h. How many minutes must she run? Hint: Use 7.5 mi/h as a conversion factor between distance and time.
ANSWER:
Step 1 of 2
Here, we are going to calculate the time required by the runner to run 10.0 Km.
Distance to be traveled by the runner = 10. 0 Km
Speed of the runner = 7.5 mi/h
Conversion of Mile(mi) to Kilometer(Km):
1 mile = 1.61 Km
Therefore, 7.5 mile = 1.61 x 7.5 = 12.1 Km
Thus speed of the runner = 12.1 Km/h
