Answer:
Speed of boat in still water is 14 km/hr and speed of current is 8 km/hr
Step-by-step explanation:
Average speed of down stream = 22 km/h
Average speed of up stream = 6 km/hr
Consider the speed of boat in still water be x km/hr and speed of current be y km/hr
As such speed of down stream would be x + y km/hr and speed of down stream would be x - y km/hr. i.e
x+y = 22
x-y = 6
by solving these two equation, we get
2x=28
x=14 km/hr
y=16-13
y=8 km/hr
Hence, the speed of boat in still water is 14 km/hr and speed of current is 8 km/hr
