Question

what was a Boat goes downstream and covers the distance between two ports in 4 hours it cover the same distance in 6 hour when it goes upstream if speed of boat is 5 km per hour then find the speed of water​

Answer 1

Answer:

Step-by-step explanation:

speed upstream         5-x     km /hr

speed downstream    5+x    km/hr

speed of boat             5        km/hr

speed of water            x        km/hr

let distance between 2 ports be 'D'

speed = distance / time

5-x = D/6

5+x =D/4

by solving

x = 1 km/hr

speed of water = 1 km/hr
