Question

A boat goes downstream from one place to another in 9 hours.it covers the same distance upstream in 11 hours.if the speed of the stream is 2km per hour,find the distance between the w places

Answer 1

Answer:

198kmhp

Step-by-step explanation:

let distance be D

speed of upstream= D/11

speed of downstream= D/9

speed of stream = (speed of upstream+ speed of downstream )/2

given speed of stream=2

D/11+D/9=4

D =198 KMPH
