Question

in a river the speed of boat in downstream is twice as speed of boat in upstream if boat takes 12 hours to go 32 kilometre from a to b and return to a by travelling same distance then find the speed of boat in still water​

Answer 1

Answer:

4/3kmph

Step-by-step explanation:

Given that the speed of boat in downstream is twice as speed of boat in upstream.

Let the speed of boat in upstream =x

then speed of boat in downstream will be 2x

speed = distance/time

Here the given distance and time are total distance travelled to upstream and downstream, 32kms in 12 hours

Speed of boat in upstream + speed of boat in downstream = distance/time

x+2x=32/12

3x=8/3

x=8/9

speed of boat in still water= (Speed of boat in upstream + speed of boat in downstream)/2

speed of boat in still water= 32/12 *1/2 = 4/3 kmph
