Question

an elevator descends into a mine shaft at the rate of 5m./min. if the descend start from 20m above the ground the how long will it take to reach 2/50m​

Answer 1

Answer:

50m/2 = 25m

Speed = 5m/min

Step-by-step explanation:

If the elevator starts the descend from 20m above the ground, then -

Total distance to be covered by the elevator = 25m+20m

                                                                            = 45m

Time taken = 45m/5 = 9 minutes
