Answer:
7/3
Step-by-step explanation:
The distances have the ratio ...
(Q -P) = (2/3)(R -P)
Q = P +(2/3)R -(2/3)P = (2R +P)/3
Qy = (2Ry +Py)/3 = (2·0 +7)/3 = 7/3

p(80+60)=560
p(140)=560
560/140 = 4 hours
the answer are x=4y-20
and x represents the independent variable and y represents the dependent variable
