Current implementations of the ‘WiMAX’ wireless technology can support 2 Mbps connections at a distance of 10 km; calculate the propagation delay caused by the transmission time alone for a signal to travel 10 km.). Give your answer in seconds and in scientific notation accurate to 2 decimal places.

c = about 3*10^8 meters/second
10 km = 10^4 meters
delay time = distance/speed = 10^4/(3*10^8)
= (1/3)*10^4 = 0.000033 seconds
= 0.333*10^4 = 3.33 *10^5 seconds
