Answer:
25 seconds (rounded up to nearest one second)
Explanation:
Cheetah's speed = 91.8 km/h
Gazelle's speed = 77.9 km/h
Both animals are running at full speed with the gazelle 97.3 m ahead.
Converting their respective speeds to m/s ;
Cheetah's speed = = 25.5 m/s
Gazelle's speed = = 21.6 m/s (correct to one decimal place)
Assuming the gazelle stops, cheetah will run at 25.5 m/s - 21.6 m/s = 3.9 m/s to catch its prey (gazelle).
Time = distance ÷ speed
The time cheetah will take to catch its prey = 97.3 m ÷ 3.9 m/s = 24.94871795 s = 25 seconds (rounded up to nearest one second)
