A car is traveling at an average speed of 70

m/s. How many km would the car travel in

6.5 hrs?

1 km = 1000 m

1 h = 3600 s

3.6 km/h = 3600 m / (3600 s) = 1 m/s

Thus,

70 m/s = (70 / 1000) km / ((1 / 3600) h) = (70 * 3600 / 1000) km/h =

70 * 3.6 km/h = 252 km/h.

The car travelling at 252 km/h for 6.5 h will cover a distance d:

d = 252 km/h * 6.5 h =

1638 km.
