Question

If a pipe removes water at some distance with a speed of 2m/sec. In time 2.0minutes.Then find the distance up to which the water reach the far point?

Answer 1

distance = time x speed
              = (2 x 120) x 2    (∴ i toke 2 x 120 because they have told 2 m/sec 
                                                so 2 min is equal to 120 sec)
              = 240 x 2
              = 480 m             

∴ after 480 meters the pipe reaches the far point.
