Question

An elevator descends into a mine shaft at the rate of 5 m/min. If the descent



starts from 15 m above the ground level, how long will it take to reach -250 mı?

Answer 1

Answer:

Step-by-step explanation:

If the descent starts from 15 m above the ground level how long will it take to reach -250 m?

The distance to be descended by the elevator = (-250) - (+15) = - 265m

rate = begin mathsize 16px style fraction numerator distance space over denominator time end fraction

end style

- 5 = (-265) ÷ x

Therefore x = (-265) ÷ (-5)= 53 minutes
