Chapter 1, Problem 26P

Estimate how many hours it would take to run (at 10 km/h) across the U.S from New York to California.

To determine

Answer to Problem 26P

The time that would be taken to travel the distance across the U.S. from New York to California.

Solution

482.8 h

Explanation of Solution

Given:

  $\text{Speed = 10 km/h}$

Formula Used:

  $\text{Speed = }\frac{\text{Distance}}{\text{Time}}$

Calculations:

Distance from New York to California by road: 3000 miles (approximately)

Distance in km:

  $\text{1}\text{mile =1}\text{.60934 km }$

  $\text{3000 }\times \text{ 1}\text{.60934 km = 4828 km}$

  $\begin{array}{l}\text{Speed = }\frac{\text{Distance}}{\text{Time}}\\ \text{Time = }\frac{\text{4828}\text{km}}{10\text{km/h}}\text{ =482}\text{.8}\text{h}\end{array}$

Conclusion:

The time that would be taken to travel the distance across the U.S. from New York to California is 482.8 h.
