Speed of the boat = u
speed of the current = v
in downstream,
u - v = 105/5
u - v = 21
in upstream
u + v = 105/7
u + v = 15
add both equations
2u = 36
u = 18
v = -3
so
speed of the boat = 18 km/h
speed of the current = 3 km/h
Answer:
y intercept: (0, 0.4)
x intercept: (0.3, 0)
Step-by-step explanation:
This is all based on observation. If you look at the graph, you see that the x intercept is (0.3, 0) and the y intercept it (0, 0.4)
Yes 3/11 is greater than 3/13
