Step-by-step explanation:
Distance descended is denoted by a negative integer,
Initial height =+20 m
Final Depth =−350 m
Total distance to be descended by the elevator =(−340)−(+20)=−360 m
Given, the time is taken by the elevator to descend −5 m=1 minute
Thus, time taken by the elevator to descend −360 m= (−5)(−360)
[from the formula : speed= time×distance ]
=30 minutes
