As speed is 72 x 1000/3600 = 72000/3600=20m/s
speed = distance /time so time =distance /speed here distance is 800m so 800/20= 40second is the answer........Hope it's helpful ________Mark as Brainliest

Step-by-step explanation:
As speed is 72 x 1000/3600 = 72000/3600 = 20m/s
Speed = Distance /Time
So time = Distance /Speed
Here distance is 800m
