Question

A cheetah runs a distance of 350meters in 50seconds.calculate the speed of cheetah in m/s,and km/h​

Answer 1

Answer:

7m/s or 25.2km/h

Explanation:

speed (v) = distance(d)/time(t)

∴ v = 350m/50s = 7m/s

d = 350m = (350/1000)km = 0.35km (∵ 1m = 1/1000 km)

t = 50 seconds = 50/60 minutes = (50/60)÷60 hours = 50/3600 h = 1/72 h

∴ v = 0.35km/(1/72)h = 25.2 km/h
