Question

an escalator moves towards the top level at the rate of 11 ft.sec and its length is 140 feet if a person walks on the moving escalator at the rate of 3 feet second towards the top level how much time does he take to cover the entire length

Answer 1

Step-by-step explanation:

Given an escalator moves towards the top level at the rate of 11 ft sec and its length is 140 feet if a person walks on the moving escalator at the rate of 3 feet second towards the top level how much time does he take to cover the entire length

• Now we need to use the concept of relative velocity. According to the question the person moves at the rate of 3 ft/s and 11ft/s which will be 14 ft/s
• Length of the level is 140 ft
• So speed = distance / time
• Or time taken = distance / speed
•                         = 140 / 14
•                        = 10 secs

So the time taken to cover the entire length will be 10 secs.
