Find Velocity!

A car travels 25 km in 0.5 hours. What is its average speed in m/s? (Find velocity)

1 Km=1000 meters X 25=25,000 meters that the car travelled. But it did that in 1/2 an hour.

1. 25,000 / 1/2=25,000 x2=50,000 meters per hour. But 1 hour=60 x 60=3,600 seconds
2. So, we divide 50,000 meters/ 3,600 seconds=13.8888..... meters per second.
