A person on a moving sidewalk travels 56 feet in 8 seconds. The moving sidewalk has a length of 140 feet. How long will it take to move from one end to the other?

The answer is : 20 seconds

Step-by-step explanation:

First, we are told that it takes the person 8 seconds to travel 56 feet, hence, we will find the time it takes to travel one foot.

56 feet = 8 seconds

∴ 1 foot = 8/56 seconds

Next, we are told that the length of the sidewalk is 140 feet, therefore walking from one end of the sidewalk to the other is the the same as walking 140 feet, and this is calculated thus:

1 foot = 8/56 seconds (calculated above)

∴ 140 feet = 8/56 × 140 = 20 seconds
