Problem

A signal from a space ship reaches the ground in 5 minutes. What was the distance of the space ship from the ground station? The speed of the signal is 3×108 m/s3 \times 10^{8} \mathrm{~m} / \mathrm{s} a) 9×107 m9 \times 10^{7} \mathrm{~m} b) 9×1010 m9 \times 10^{10} \mathrm{~m} c) 9×106 m9 \times 10^{6} \mathrm{~m} d) 3×106 m3 \times 10^{6} \mathrm{~m}
