Question

An elevator descends into a mine shaft at the rate of 6 m/min. If the
descent starts from 10 m above the ground level, how long will it take to reach –
350 m. Suppose we represent the distance above the ground by a positive
integer and that below the ground by a negative integer, then answer the
following:
(i) An elevator descends into a mine shaft at the rate of 5 metre per minute.
What will be its position after one hour?
(ii) If it begins to descend from 15 m above the ground, what will be its position
after 45 minutes?
