Chapter 1.1, Problem 63E

To determine

To complete the given statement

Answer to Problem 63E

  $\frac{\text{68mi}}{h}=\frac{\text{244800mi}}{\sec }$

Explanation of Solution

Given:

  $\frac{\text{68mi}}{h}=\frac{\text{ mi}}{\sec }$

Formula used:

Here, mi refers to minutes, h refers to hours and sec refers to second.

1 hour = 60 minutes

1 minute = 60 seconds

Calculation:

From the statement, 68 minutes per hour = x minutes per second.

To convert hours to seconds multiply by 3600

  $\Rightarrow \frac{\text{68mi}}{h}=\frac{68}{\frac{1}{60}\text{mi}}=\frac{68}{\frac{1}{60\times 60}}=\frac{68\times 3600\text{mi}}{\sec }=\frac{244800\text{mi}}{\sec }$

Conclusion:

Therefore, the statement becomes $\frac{\text{68mi}}{h}=\frac{\text{244800mi}}{\sec }.$
