Answer 1

speed of the streamer is: 26km/hr.

Step-by-step explanation:

suppose the distance between two points is "x".

and the speed of the streamer is "s".

As we know:

• distance= speed×time.

so while going downstream,

x= (s+6)× 20.

while going upstream.

x= (s-6)× 32.

so from above equations, we get:

(s+6)×20=(s-6)×32.

20s+120=32s-192.

32s-20s=120+192.

12s=312.

s=312/12.

s=26.

hence, the speed of the streamer is 26km/hr.
