Answer 1

Step-by-step explanation:

So the total descent is 10+350=360m

distance=360m

Speed=6m/min

time=?

Speed= distance/time

6= 360/time

time 60 mins

= 1 hour

pls mark as brainliest

Answer 2

Answer:

$\mathfrak{\huge{\orange{\underline{\underline{Answer :}}}}}$

Total distance elevator has to travel = Initial position- Final position.

=10-(-350)

=10+350

=360 meters.

Now,

Elevator descends at the rate of 6m/min

Therefore elevator travels 6m in 1 min.

Elevator travels 1 m in 1/6 min

Elevator travels 360m in = 1/6×360 mins

= 60 mins.

1 hour.

Therefore the elevator takes 1 hour.
