Question

A person on a moving sidewalk travels 24feet the in 7 seconds. The moving side walk has a length of 180 feet. How long will it take to move from one end to the other?

Answer 1

Given:

A person on a moving sidewalk travels 24 feet the in 7 seconds.

The moving side walk has a length of 180 feet.

To find:

Time taken by the person to move from one end to the other.

Solution:

A person on a moving sidewalk travels 24feet the in 7 seconds.

The speed of the person is

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

$\text{Speed}=\dfrac{24}{7}$

$\text{Speed}=\dfrac{24}{7}$

The moving side walk has a length of 180 feet.

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

$\text{Time}=\dfrac{180}{\dfrac{24}{7}}$

$\text{Time}=\dfrac{180}{1}\times \dfrac{7}{24}$

$\text{Time}=52.5$

Therefore, the time taken by the person to move from one end to the other is 52.5 seconds.
