Question
An athlete runs an 800 m race in 96 seconds. His speed
(in km/h) is:Solution
ATQ, Formula used: Speed = Distance/Time Converting speed from m/s into km/h a m/s = [a × (18/5)] km/h Calculations: Speed of the athlete = 800/96 ⇒ (25/3) m/s Converting the speed from m/s into km/h ⇒ (25/3) × (18/5) ⇒ (5/3) × 18 ⇒ 5 × 6 ⇒ 30 km/h ∴ The speed of the athlete is 30 km/h
