Answer:
Step-by-step explanation:
- Speed in one direction = 40 km/h
- Speed on return = x
- Average speed = 60 km/h
Let the distance be d
<u>Average speed </u>
- 2d/(d/40 + d/x) = 60
- d/40 + d/x = 2d/60
- 1/40 + 1/x = 1/30
- 1/x = 1/30 - 1/40
- 1/x = (4-3)/120
- 1/x = 1/120
- x = 120 km/h

Answer:
y=5/3x-13
Step-by-step explanation:
We must use the point-slope form(parallel lines have the same slope, remember that!)
y-y1=m(x-x1)
y-2=5/3(x-9)
y-2=5/3x-15
y=5/3x-13
