1.	An elevator descends into a mine shaft at the rate of 5m/min.If the descend starts from 15m above the ground level,how long will it to reach -360m
Answer» Step-by-step explanation: ans: an elevator descends into the MINES SHAFT at the rate of = 5m/min , it has to GO into the depth= 360m therefore 360 should be divided by 5 that is =72 but it doesn't from 15 metre above the ground level so I gained 15 metres should be divided by 5 and the ANSWER what your get should be added to 72. That is = 15÷5=3 = 3 therefore that is 72 + 3 is equals to 75 therefore the elevator TAKES 75 minutes to reach the mindfact at the rate of 5 metre per minute

Step-by-step explanation:

ans: an elevator descends into the MINES SHAFT at the rate of = 5m/min

, it has to GO into the depth= 360m

therefore 360 should be divided by 5 that is =72

but it doesn't from 15 metre above the ground level so I gained 15 metres should be divided by 5 and the ANSWER what your get should be added to 72. That is = 15÷5=3

= 3

therefore that is 72 + 3 is equals to 75 therefore the elevator TAKES 75 minutes to reach the mindfact at the rate of 5 metre per minute
