Question

the speed of the boat in steel water is 10 km / hour if it can travel 26 km downstream and 40 km upstream in the same time find the speed of stream.​

Answer 1

Answer:

Step-by-step explanation:

let the speed of the stream is x km/h.

downstream speed = 26 /10+x

upstream speed = 14/10-x.

according to question.

time of each stream is same so,

26/10+x = 14 / 10 -x

260 -26x = 140 + 14x

x = 3 km /h .

thus,

the speed of stream is 3 km/h.
