Question

A car drove 12 miles in 0.2 hours. a.) How fast was the car traveling in miles per hour? b.) At that rate, how long did it take the car to travel 204.75 miles?

Answer 1

Comparate velocity and time

Magnitudes operations

Part a) How fast ( velocity) was car traveling

V = 12 miles/ 0.2 hours = 12/ (2/10) = 12 x 10 / 2 = 120/2 = 60 miles/hour

Part b). How long ( Time)) did take to travel 204.75 miles

Distance = Velocity x Time

Time = Velocity/ Distance = 60 (miles/hour)/ 204.75( miles) = 0.293 Hours

Time = 0.293 hours = 18 minutes
