Answer» Let x be the speed of the steamer in still water Speed of the stream = 5km/h (Given) Downstream: Speed = (x + 5) Time = Distance ÷speed Time = 90 /( x + 5) Upstream: Speed = ( x - 5) Time = Distance ÷Speed Time = 60/( x - 5) Since the time taken for upstream and downstream is the same: 90 /( x + 5) = 60/( x - 5) 90 (x - 5) = 60 (x + 5) 90x - 450 = 60x + 300 30x = 750 x = 25 km/h Answer: The speed of the steamer in still water is 25km/h

Answer»

Let x be the speed of the steamer in still water

Speed of the stream = 5km/h (Given)

Downstream:

Speed = (x + 5)

Time = Distance ÷speed

Time = 90 /( x + 5)

Upstream:

Speed = ( x - 5)

Time = Distance ÷Speed

Time = 60/( x - 5)

Since the time taken for upstream and downstream is the same:

90 /( x + 5) = 60/( x - 5)

90 (x - 5) = 60 (x + 5)

90x - 450 = 60x + 300

30x = 750

x = 25 km/h

Answer: The speed of the steamer in still water is 25km/h
