Question

Suppose your on the bus and walking from the back to the front while the bus is moving at 10 mph. If you walk at 2 mph, what is the speed in mph?

Answer 1

Given data:

* The speed of the bus is 10 mph.

* The speed of the person in the bus is 2 mph.

Solution:

As the lecture hall is in state of rest with respect to Bus,

Thus, the speed of the person walking inside the bus with respect to the lecture hall is,

$\begin{gathered} S=\text{speed of bus+spe}ed\text{ during walk} \\ S=10\text{ mph + 2 mph} \\ S=12\text{ mph} \end{gathered}$

Thus, the speed relative to the lecture hall is 12 mph.
