Answer:29.41 m/s

Explanation:

Given

Height of cliff 22.8 m

Height of river bank=2.4 m

width of river=60.0 m

Car can considered as projectile

Time travel to cover vertical distance=22.8-2.4=20.4 m

h=ut+\frac{at^2}{2}

20.4=0+\frac{gt^2}{2}

t^2=4.163

t=2.04 s

Range=60 m

Let u be the speed of car

ut=60

u=\frac{60}{2.04}=29.41 m/s
