slope = (1+2)/(1-0) = 3
parallel lines have same slope
so answer

Is this simultaneous equations?
if yes then the first step is
make one of the unknown as the subject
For the first one, it would be 5/3 and 19/3
the second one would be 40
Answer:
wilma is 22.5 mph
fred is 25.5 mph
Step-by-step explanation:
Time:40 minutes, or 2/3 hours
Speed:
Fred:x+3
Wilma: x
Distance:32 miles
2/3(x+x+3)=32
2/3(2x+3)=32
1 1/3x+2=32
4/3x=30
x=22.5
wilma is 22.5 mph
fred is 22.5+3= 25.5 mph
