Christ is on a train. He sees a truck that is going parallel road in the opposite direction and passes his window in 6 sec. since his first sight. Later on, he sees the train passing through a bridge of 180ft in 12 secs. If the length of the truck is 168ft, what is the speed of the truck in mph?

The train's speed wrt the Earth is 180/12 = 15 ft/sec
The train's speed wrt the truck is 168/6 = 28 ft/sec
The truck's speed wrt to Earth = 13 ft/sec
