Answer:
1/2
Step-by-step explanation:
Slope is rise over run. Starting from (0, 2), go up and move right until you reach another point. So you go up 1 unit and move right 2 units.
Let the speed for the first 12 mi be x mi/h, the speed for 18 mi was (x+4) mi/h
thus given that
time=distance/speed
the average time will be:
3=(12+18)/(x+x+4)
3=30/(2x+4)
solving for x we get
3(2x+4)=30
6x+6=30
6x=24
x=4 mi/hr
Answer: 12 mi/hr
There are many like
1(10)+10-1=19
18+1=19
30-11=19

Each method works diffrently the angles inside them is what matters.
