Chapter 11.2, Problem 45CCR

To determine

To find: At what time will the storm hit.

Answer to Problem 45CCR

Time to reach is $4:00$ PM

Explanation of Solution

Given information:

Distance $=d=150$ miles from the town

Speed $=s=30$ miles per hour.

  $t=\frac{d}{s}$

At $11.00$ A.M storm starts heading towards the town

Given

  $t=\frac{d}{s}$

On substituting values

We get

  $\begin{array}{l}t=\frac{d}{s}\\ \Rightarrow t=\frac{150}{30}\\ \Rightarrow t=5\end{array}$

Therefore

  $t=5hr$

So, it takes $5hr$ to reach the coast at this speed.

Storm started at $11.00$ A.M and it takes $5hr$ to reach the coast

Therefore,

Time to reach is $4:00$ PM
