Question

A train is moving north at 90 km/hr. A passenger walks towards the front of the train (north) at 5 km/hr relative to the train. What is the passenger's velocity relative to the ground?

Options

• 85 km/hr North

• 95 km/hr North

• 5 km/hr North

• 90 km/hr North

Answer 1

95 km/hr North

Since the passenger and the train are moving in the same direction, their velocities with respect to the ground add up.
