Question

A turtle is riding a plane moving forward at 750 m/s. The turtle walks towards the back of the plane at a rate of 2 m/s. What is the resultant velocity of the turtle?

Answer 1

Since the turtle is moving towards the back of the plane, we can draw the following velocity vectors:

Since the velocities have opposite directions, the resulting velocity is the subtraction of these velocities:

$\text{velocity}=750-2=748\text{ m/s}$
