It will take 53.3 x 10^-5 sec for a radio signal to travel 160 km from a transmitter to a receiving antenna
We take d to be 160 km = 160 x 10^3 m
Then
time = distance/speed
t = d/c
t = 160 x 10^3 m / 3 x 10^8 m/s
t = 53.3 x 10^-5 sec
Hence, it will take 53.3 x 10^-5 sec for a radio signal to travel 160 km from a transmitter to a receiving antenna
