A van was driven at a speed of 90 km/h along a straight road. Convert the unit to m/s? Solution: 1 km = 1000 m, 1 h = 3600 s. 90 km/h = 90 km x 1000 m x 1 h = 25 m/s. h 1 km 3600 s. Example 2: The speed of sound in the air is 330 ms-1. Convert the unit to cm/min? Solution: 1 m = 100 cm, 1 min = 60 s ................
