Chapter 1.1, Problem 65E

To determine

To complete the given statement

Answer to Problem 65E

  $\frac{8km}{\min }\approx \frac{\text{480000m}}{h}$

Explanation of Solution

Given:

  $\frac{8km}{\min }\approx \frac{\text{ m}}{h}$

Formula used:

Here, min refers to minutes, m refers to meters, km refers to kilometers and h refers to hours.

1 kilometer = 1000 meters.

1 hour= 60 minutes

Calculation:

From the statement, 7 gallons per minute = x quarts per second.

To convert kilometers to meter, multiply by 1000 and to convert minutes to hours, divide by 60.

  $\Rightarrow \frac{8km}{\min }\approx \frac{\text{ m}}{\frac{1}{60}h}=\frac{\text{8}\times 1000\times 60\text{m}}{h}\approx \frac{\text{480000m}}{h}$

Conclusion:

Therefore, the statement becomes $\frac{8km}{\min }\approx \frac{\text{480000m}}{h}.$
