Question 496430: I have this really weird homework question that I need help on.
A passenger on a train traveling at 135 km/hr walks towards the back of the train at a rate of 7 km/hr. What is the passenger's rate of travel with respect to the ground?
Please help as soon as possible.

He's moving in the opposite direction, so his speed is subtracted.
135 - 7 = 128 km/hr
