Answer:
The slope is 2/3
Step-by-step explanation:
To find the slope of a line
m = (y2-y1)/(x2-x1)
= (1--1)/(0--3)
= (1+1)/(0+3)
= 2/3
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:
