Antelope 4440

The cheetah began to chase the antelope, and there was a distance of 120 m between them. Although the antelope ran at 72 km/h, the cheetah caught up with it in 12 seconds. How fast was the cheetah running?

Correct answer:

v =  30 m/s

Step-by-step explanation:

v1=72 km/h m/s=72:3.6  m/s=20 m/s t1=12 s s2=120 m  v1 t1+s2=v t1 20 12+120=v 12  12v=360  v=12360=30  v=30=30 m/s
