Question

a particular descends at rate of 25 m per min. at a particular time, it was at a height of 1850m above the ground level. how long will it take to reach the height 250m above the ground level​

Answer 1

Answer:

Step-by-step explanation:

a particular descends at rate of 25 m per min. at a particular time, it was at a height of 1850 m above the ground level. how long will it take to reach the height 250 m above the ground level​

Given height at which parachute was flying will be 1850 m

Now parachute descends to a height will be 250 m

So height of the parachute descended will be 1850 – 250 = 1600 m

Rate at which parachute descends will be 25 m per min

So time taken to descend 250 m height will be  

Speed = dis / time

Time = distance / speed

  Time = 1600 / 25

= 64 min

So the parachute takes 64 min to reach to a height of 250 m

Answer 2

Answer:

64m

Step by step explanation:

height of parachute at a particular time =1850m

time taken to reach the height of ground level= 250m

=1850-250

=1600

parachute descend at the rate of= 25m

Speed = dis/time

Time= dis/speed

Time = 1600/25

=64m
