Question

A car is traveling at a rate of

50
meters per second. What is the car's rate in kilometers per hour? How many kilometers will the car travel in
4
hours? Do not round your answers.

Answer 1

50 * 14,400 = 720,000 /4 = 180,000 / 1000 = 180km/h

Answer 2

50 meters per second

3600 seconds per hour

1000 meters per km

50/1000 = 0.05

1/3600 = .0002777

0.05/0.0002777 = 180km per hour

180*4 = 720km in 4 hours
