Question

A lift travels at the rate of 4 m/sec. If
the descent starts from 20 m above the
ground level, how long will it take to
reach-220 m?
Please reply me ​

Answer 1

ANSWER :-

We know that,

Time = Distance / Speed

Distance = 220 - 20 = 200 m

Speed = 4 m/s

Time = 200/4 = 50 seconds

The lift will take 50 seconds to reach 220 m.

Answer 2

Answer:

1 min

Step-by-step explanation:

Total travel of lift

• 20 m above ground + 220 m below ground = 240 m

Speed

• 4 m/sec

Time

• 240 m / 4 m/sec = 60 sec = 1 min

Answer is 1 minute
