Chapter 6.3, Problem 13PPS

To determine

To convert the $\text{55}$ miles per hour in feet per second

Answer to Problem 13PPS

  $\text{55m/h}=80.67\text{ feet/second}$

Explanation of Solution

Given data:

Velocity=55 miles per hour

Calculation:

We know that relation between mile per hour and feet per seconds is given as

  $\begin{array}{l}\text{1 mile per hour=}\frac{\text{5280 feet}}{\text{3600 seconds}}\\ \text{1 mile per hour}=1.467\text{ feet per seconds}\\ \text{Therefore,}\\ \text{55 miles per hour}=\text{ 55}\times \text{1}\text{.467 feet per seconds}\\ \text{55miles per hour}=\text{80}\text{.67 feet per seconds}\end{array}$

Conclusion:

Therefore, the velocity $\text{55}$ miles per hour is equal to $\text{80}\text{.67}$ feet per second
