3,750 sec
At 35 mph you will travel about 154 feet in three seconds.
There are only 31,536,000 seconds in a year. So, light can only travel for 31,536,000 in a year.

450 km = 450000 metres Time = Distance/Speed = 450000/120 seconds = 3750 seconds.
(450,000 meters) x (1 second/120 meters) = 3,750 seconds( 1hour 2minutes 30seconds )
Assuming a geosyncronous communications satellite, it is 35,900 km above the surface of the earth. If you are directly beneath it, a microwave will travel at the speed of light (300,000km/s) there and back through this distance. Thus: 2 * 35,900 /300,000 = 0.240 seconds. Note that this is larger if the sender and recipient are located far away, because of the angle.
