Suppose a 128-kbps point-to-point link is set up between the Earth and a rover on Mars. The distance from the Earth to Mars(when they are closest together) is approximately 55 Gm, and data travels over the link at the speed of light (3X10⁸m/s).

Calculate the minimum RTT for the link.

(b)Calculate the delay X bandwidth product for the link.

A camera on the rover takes pictures of its surroundings andsends these to Earth. How quickly after a picture is taken canit reach Mission Control on Earth? Assume that each image is 5Mb in size.
