Question

An uplift moves down words in a mine- well out the rate of 6 metre/minute. If lift starts going down wards from the height 10 m above the ground, then how much time will it take to reach – 350 m?

Answer 1

Difference between two heights = 10 m – (- 350 m)

= 10 m + 350 m

= 360 m

Rate of going downwards = 6 m/minute

∴ Time of reach at lowest point = 360/6

= 60 minute

= 1 hour.
