Answer 1

Answer:

Here is your answer

speed of boat is 18 km per hour

let the speed of steam be X kilometre per hour

speed of the boat upstream = speed of boat in water - speed of boat in still stream

therefore speed of boat upstream ( 18-x)km per hr

speed of boat down stream = speed of boat in water+speed of boat in stream= (18+x)

time for upstream journey=time of downstream journey+1hr

48x + 342 -x^2

after the calculation.....

x= 6

hence speed is 6 km per hour

please mark my answer is the brainliest

hope it is helpful for you
