Answer 1

motor boat covers a certain distance into how's going upstream it covers the same distance in 1 hour while posting if the speed to the string in c find the speed of car is still water

Answer 2

Answer:

Step-by-step explanation:

Let distance = X

Speed of boat is Y

According to Question

X/( Y-6)= 2

X=2Y-12

X-2Y=-12.......1

X/Y+6 =1

X=Y+6

X-Y=6....2

X-2Y=-12. ×1

X-Y =6 ×2

X-2Y=-12

2X-2Y=12

-X= -24

X=24

Speed of Boat in stillwater is (24-Y=6)

Y=18 km/h
