Question

pls answer it how to solve

Answer 1

find the time taken by car
time = distance /speed
and then multiply that time with speed of bird which will give you the desired distance .

Answer 2

Speeds are given in km/h
To convert speed in km/h into m/s multiply it with 5/18

Time taken by car to reach the tree is
T = Distance / Speed
= 240 m / (60 * 5/18 m/s)
= 14.4 seconds

Distance travelled by bird in 14.4 seconds is
S = Speed × Time
= (90 * 5/18 m/s) × 14.4 s
= 360 m
