A Steamer Goes Downstream From One Port To Another In 4 Hours, It Covers The Same Distance Upstream In 5 Hours. If The Speed Of The Stream Is 2km/hr,the Distance Between The Two Parts Is?

Answer»

Let the distance between the two parts be x KM

Then speed DOWNSTREAM = x/4 km/hr. 

Speed Upstream = x/5 km/hr 

Speed of the stream = ½ (x/4 –x/5) 

THEREFORE, ½(x/4 –x/5) = 2. => x/4 –x/5 = 4 => x = 80. 

Hence, the distance between the two ports is 80km.

Let the distance between the two parts be x km. 

Then speed downstream = x/4 km/hr. 

Speed Upstream = x/5 km/hr 

Speed of the stream = ½ (x/4 –x/5) 

Therefore, ½(x/4 –x/5) = 2. => x/4 –x/5 = 4 => x = 80. 

Hence, the distance between the two ports is 80km.
