The kangaroo will sprint 50m in 2 seconds as

100 meters in 4 seconds, so-

it will be 50 meters in 2 seconds. (Half of 4 is 2, and half of 100 is 50, so it will be 50 meters in 2 seconds.)

The Brainliest Answer!

distance travelled by kangaroo = 100m and 50m

time taken = 4sec and 2sec

as we know the formula of speed

Speed = 100/4sec

= 25m/sec

speed of kangaroo in the first case was 25m/sec

In the same way for the second case

Speed = 50/2sec

= 25m/sec

therefore average speed of kangaroo is 25m/sec
