Question

The height of a multistorey building is 190 m and the depth of its basement<br />is 10 m. A lift in building moves at a rate of 10 m/ 15 second. If a man<br />starts from terrace, how long will it take him to reach at bottom of the<br />basement ?​

Answer 1

5 min or 300 sec.

As total distance = 190 + 10 = 200m

And speed = 10m/15sec

Time taken from top to bottom of the building is

1 min = 40m

200m = 5 min or 300sec
