PLEASE ANSWER THIS QUESTION

An escalator moves up at the rate of 6 ft/sec and its length 20 ft. If a person walks up on the moving escalator at the rate of 2 ft/sec, how much time does he take to cover the entire length?

BRAINLIEST QUESTION

Answer 1

2.5 sec
because
the total speed 6+2
and the length is 20 m
so it will cover in 20÷8

Answer 2

Time taken to cover the entire length = Total distance/Resultant speed.

= > 20/(6 + 2)

= > 20/8

= > 2.5 seconds.

Therefore, it will take 2.5 seconds to cover the entire length.

Hope this helps!
