solve question 3 for me

3. Consider the following network: 4 Mbps 3000 KM 10 Mbps 6000 KM Assume that the data travels through the link in both directions with the speed of light( 3 x 10 meter/sec or 3 x 10 km/sec or 300,000 kilometers per second). i) What is the transmission delay if a. A sends a 500 byte packet to B b. B sends a 100 byte packet to C - ii) What is the propagation delay if a. A sends a 500 byte packet to B - b. B sends a 100 byte packet to C
