Question

a Boat goes some distance in upstream in 6 hours and cover the same distance in downstream in 4 hours is the speed of stream is 32 metre per hour then the distance is​

Answer 1

Answer:

Step-by-step explanation:

Assume distance is LCM(6,4) = 12 kms

Upstream speed = 2kmph

Downstream speed = 4kmph

Speed of boat = ( 2 + 4)/2 = 3 kmph

Speed of river = (4 - 2)/2 = 1/2 kmph

If speed of river is 3 kmph, then :

Distance = 12 x 3 /(1/2 ) = 72 kms
