Answer 1

Answer:

as speed of gazelle = 80km/h = 200/9 m/sec

speed of cheetah= 100km/h = 250/9 m/sec

let time take by cheetah be time t to catch gazelle

here in time same time let the distance covered by gaxelle in time t is x

therefore the cheetah have to cover 300+x distance

as time are equal

therefore

x/(200/9)=(300+x)/(250/9)

hence we get x= 1200 m

now the distance for cheetah is 300+1200=1500m

1500/(250/9)=54sec
