Question

A steamer goes downstream from one port to another in 9 hours. It covers the same distance upstream in 10 hours. If the speed of the stream be 1 km/h, find the speed of the steamer in still water and the distance between the ports​

Answer 1

Answer:

Hey friend,

Here is the answer you are searching for,

Let speed of steamer in still water be x,

=>Speed downstream = x+1

=>Speed upstream = x-1

Time upstream = 10 hours

Time downstream = 9 hours

=> Distance upstream = 10(x-1)

=> Distance downstream = 9(x+1)

Distance will be same,

=> 9(x+1) = 10(x-1)

=> 9x+9 = 10x-10

=> x = 19 km/h

Therefore,

Speed of steamer in still water = 19km/h.

HOPE IT HELPS YOU.

Answer 2

Answer:

Step by step explanation:

Distance = 9(x+1)

= 9(19+1)

=9×20=180 km/ hr
