Chapter 6.3, Problem 4GP

To determine

To convert: The skating rate 12 meter per second of a gold medal winner into miles per hour.

Answer to Problem 4GP

Skating rate in miles per hour is 26.84.

Explanation of Solution

Given information: 

Player O won skating gold in US winter Olympic at the rate 12 meter per second.

Concept used: Use following conversion formulae first:

1 meter $=0.00062137$ miles

1 second $=\frac{1}{3600}$ hours

Calculation: Using above conversion formula,

  $12\text{ meters}=12\times 0.00062137=0.007456\text{miles}$

So, given rate is calculated as follows:

  $\begin{array}{c}\Rightarrow \frac{12\text{meter}}{1\text{second}}=\frac{0.007456}{\frac{1}{3600}}\\ =26.84\text{miles per hour}\end{array}$

Thus, O skating record in winter Olympic is 26.84 miles per hour.
