Question

if a boat cover 25km upstream and 40km downstream in 5hrs and 40km upstream and 25km downstream in 8hrs then find the speed of still water​

Answer 1

$\huge \sf \bf {\boxed{\underline {\red{\underline {✠Aɴʂᴡᴇʀ࿐ :−}}}}}$

Let the speed of the boat in still water be r km/h and that of the stream be y km/h. Then Solving equations u and ui we get r = 8 and y =3. Hence speed of the boat in still water is 8 km/h and speed of the stream is 3 km/h.

Answer 2

Answer:

Probably the answer! :)

Step-by-step explanation:

Let the speed of the boat in still water be r km/h and that of the stream be y km/h. Then Solving equations u and ui we get r = 8 and y =3. Hence speed of the boat in still water is 8 km/h and speed of the stream is 3 km/h.
