Answer :
Distance descended is denoted by a negative integer,
Initial height =+10 m
Final Depth =β350 m
Total distance to be descended by the elevator =(β350)β(+10)=β360 m
Given, the time is taken by the elevator to descend β6 m=1 minute
Thus, time taken by the elevator to descend β360 m=
(β6)
(β360)
β
------- [from the formula : speed=
time
distance
β
]
Answer =60 minutes
