Heya user,
1 hour = 3600 sec. --->> 10 sec = 1/360 hour
1km = 1000 m -->> 200m = 1/5 km
=> Cheetah's speed = Δx/Δt = 200m / 10s = [ 1/5 ] / [ 1/360 ] km / h
=> Cheetah's speed = 360/5 = 72 km/h <--- Desired Ans..

Distance covered in 10 sec= 200m
Distance covered in 1 sec = 200/10 = 20m
This means that speed of cheetah is 20m/sec
Speed in km per hour=20*18/5 =360/5=72km/h
Hope it will help you......
