This is a standard 'distance = rate #xx# time' problem


The key to this problem is microwaves travel at the speed of light, approx #2.99 xx 10^8 m/s#. So, if a microwave is pointed at an object and the total time required for the echo (reflection) to be received is accurately measured, the distance to the object can be easily calculated.
