a car is traveling at a rate of 41.2 megameters/hr. what is the rate in cm/s?

1 Megameter = 10^6 meters

1 meter = 100 cm

I'll convert megameters to meters for you.

(41.2 megameters/hr)(10^6 meters/1 megameter)(100 cm/ 1 meter)=___m/hr

notice how all the units cancel to m/hr

now that you have m/hr, please convert hr to sec, knowing that 1 hour = 60 min, 1 min = 60 sec
