long will it take to descend to a height of 500 m?
​

Answer 1

Answer:133333

Step-by-step explanation:

Answer 2

Answer:

20

Step-by-step explanation:

Let the time taken be x minutes.

So, total height descended = 75x m

Total height which is to be descended = (2000-500) m =1500 m

Therefore ,

75x =1500

=> x= 1500/75 =20

Hence total time taken is 20 minutes
