Question

Light travels from the sun to the earth, a distance of 144,000,000,000 meters, in 480 seconds. Calculate the approximate velocity of light in the direction it travels toward the earth.

Answer 1

Light travels at a constant rate of 300,000,000 m s

. This can be determined by dividing the distance (144,000,000,000 meters) by the time (480 seconds). That's pretty fast. In fact, nothing can travel any faster than this. Ever.

Answer 2

144.000.000.000÷480

=300.000.000 m/s

=300.00 km/s
