Question

For a radio signal to travel 150 km from the transmitter to a receiving antenna, it takes :

Answer 1

$5 \times {10}^{ - 4}$
Radio signals also have speed of light.

Therefore we know that,

Time = Distance/speed.

time =
$(150 \times {10 }^{3} ) \div (3 \times {10}^{8} )$
Time=
$5 \times {10}^{ - 4}$
seconds
