Ans:
Since Distance = Speed * Time & Therefore Time = Distance / Speed.
Given, Distance = 45 km = 45 * 1000 m = 45000 m
& Speed = 3 * 108 ms-1.
So, Time taken by the radio signal to return back from the aeroplane
45000
= ---------
3 * 108
15000
=> Time = --------
108
15
=> Time = ----
105
15
=> Time = --------- = 0.00015 =
Ans.
100000
