Answer:

Answer :-

Let the speed of steamer = X km/hr

Speed of stream = 1 km/hr

Downstream speed = (X+1) km/hr

Upstream speed = (X-1) km/hr

Distance = Speed x Time

=> 1 (X+1) = 10 (X-1)

=> 1X +1 = 10X -10

X= 10+1= 11km/hr

Therefore, speed of the stream is 11km/hr

Distance travelled = 1 (X+1) 1 x 20 = 20km
