Question

Traveling to the three important locations in Bobby’s world involves a 34.6 mile journey. Without traffic, GoogleMaps predicts that this path will take 42 minutes of driving in a car. What is the assumed average speed per hour that GoogleMaps is using for this calculation? Show all of your work as if you were to explain this to a grade school student.

Answer 1

speed = total distance/total time
but 42 minutes = 42/60 hours or 7/10 hour

avg speed = 34.6/(7/10)
= 34.6 (10/7) = .... mph

Answer 2

So it's 42/60 = 0.70

Then, 34.6/0.70 = 49.42

Answer is 49.42
