Sign in nowSpeed of the deer = 108 km/h = 108 × (5/18) = 30 m/s Distance covered by the cheetah in 12 seconds = 66 metres + distance covered by the deer in 12 seconds = 66 + 30 × 12 = 66 + 360 = 426 metres So, speed of the cheetah = 426/12 = 35.5 m/s Speed of the zebra = 30 × (80/100) = 24 m/s So, relative speed of the cheetah with respect to the zebra = 35.5 – 24 = 11.5 m/s Hence, time taken by the cheetah to catch the zebra = 115/11.5 = 10 seconds
