Question

If I’m walking on a train going 10 mph, and I’m going 2 mph, what is my speed?

Answer 1

Given data

*The speed of the train is u = 10 mph

*The speed of the person is v = 2 mph

The actual speed of the person is calculated as

$\begin{gathered} v_p=u+v \\ =10+2 \\ =12\text{ mph} \end{gathered}$
