Question

.The speed of a boat in still water is 8km/hr. It can go 15 km upstream and 22 km
downstream in 5 hrs. Find the speed of the stream.

Answer 1

Answer:

Let the speed of boat be x

the speed of stream be y

therefore, downstream = x+y

upstream= x-y

15^x-y= 8 ......1eq

similarly , 22^x+y=5

and solve that
