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}=\frac{\text{Distance}}{\text{Time}}`

`\text{Speed}=(24)/(7)`

`\text{Speed}=(24)/(7)`

The moving side walk has a length of 180 feet.

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

`\text{Time}=(180)/((24)/(7))`

`\text{Time}=(180)/(1)* (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.
