Question

b) An elevator descends into a mine shaft at the rate of 7 m/min. If it starts from
5 m above the ground level. How long will it take to reach 205 m down the
earth?​

Answer 1

Step-by-step explanation:

If 205m is the distance the it will be -205m.Now speed of the elevator is7m/min,starting distance=5m so, 7×5m=35m/min.divide it with -205m

so,-205÷35m=-51m
