Answer:
Given :-
Speed of elevator = 8 m/minute
Initial height of elevator = 10 m
Final depth of elevator = -350 m
To Find :-
Time taken
Solution :-
Thus, distance to be descended by elevator = -350 + (-10 ) = -360 m
Time taken by elevator to descend -8 m = 1 minute
Time taken by the elevator to descend -360 m = -360 ÷ (-8)
= 40 minutes
Thus, time = 40 minutes
