The Speed of Light Measured with a Pulsed Laser

A laser is pulsed at 1 MHz, and the laser light pulses are bounced off of a mirror and then detected by a fast detector. The time between the sending and recieving pulses is used to time the transit of light. The answer is 2.99792458×1010 cm/s, what is the question?
