Question

a boat goes downstream in 8 hrs it cover same distance upsteam in 12 hrs . if the speed is 2 km/hr .find speed of steam in still water , distance covered by boat

Answer 1

this is the answer for this

Answer 2

Hey dear friend, here is your answer.................. :-)


Let the speed of the boat in still water be x km/hr

Speed of boat in upstream = (x-2)
Speed of boat in downstream = (x+2)

And, Distance = s×t

A/Q

8(x+2)= 12(x-2)
8x+16= 12x -24
16+24=12x-8x
40= 4x
x= 10.

Distance = 8(10+2)

= 8× 12
=96. Km. Ans

Hope it helps......!!
