Question

A motor boat takes 2 hours to travel a distance 9 km. down the current and it takes 6 hours to travel the same distance against the current. The speed of the boat in still water and that of the current (in km/hour) respectively are

Answer 1

Answer:

So here's your answer

Step-by-step explanation:

Let the speed of boat in still water = x & speed of current = y

x+y

a=2

9=2x+2y ........ (i)

x−y= 9

=6

9=6x−6y ........ (ii)

Add (i) & (ii)

4x=12

x=3km/hr

y= 2/3km/hr
