Answer 2

Answer:

Step-by-step explanation:

Let ,the let the speed of the steamer be X

Given the speed of stream 1 kilometre per hour

Speed downstream x-1

speed upstream x+1

Time taken to go downstream to go 9

Time taken to go upstream 10

Let the distance be D

Distance upstream 10 multiply X - 1

Distance downstream 9 multiply X + 1

According to question distance in both cases are same

9 X + 9 = 3 X + 10

9 + 10 = 3 x- 9 X

19km/h =X

Distance= 9 X + 9

=9 × 19 + 9

=171+ 9

=180km
