In a communication network, Node A is connected to Node B by a point-to-point link, whose data rate is 5 Mbps and its length is 31 Kilometers. Node B is connected to node C by another point-to-point link, whose data rate is  6 Mbps and its length is 48 Kilometers. A 10000-bit packet is sent from node A to node B and from there to Node C. 

How long does it take between the time the first bit of this packet leaves node A until the last bit of it arrives at node C? 

Calculate the time in milliseconds to the first decimal point.

Assume all nodes operate in store-and-forward mode; i.e. they receive a packet in full before transmitting it out. The speed of light is 200,000 Km/s.
