A space probe on the surface of Mars sends a radio signal back to the Earth, a distance of 9.90 ✕ 107 km. Radio waves travel at the speed of light (3.00 ✕ 108 m/s). How many seconds does it take for the signal to reach the Earth?

3.00 x 10^8=300,000,000ms

convert into km

i km=1000m

?     =300,0000,000m

300,000km

distance between mars and earth=99,000,000km

1 sec waves travel 300,000km

99,000,000/300,000

=330sec

=5 mins 30 secs
