Answer:

Let the speed of the streamer =xkm/h

The speed downstream =(x+5)km/h and

The speed upstream =(x−5)km/h

According to the given problem ,

x+5

90

=

x−5

60

On cross multiplication , we get ,

90(x−5)=60(x+5)

90x−450=60x+300

90x−60x=300+450

We get,

30x=750

x=

30

750

x=25

Therefore , the speed of the streamer in still water is 25km/h
