Question 1175234: Two planes leave the same airport at the same time and travel in opposite directions. After 1.5 hours, they are 748.5 kilometers apart. The rate of the faster plane is 5 kph less than thrice that of the slower plane. Find the rate of each plane

.

r is the rate of the slower plane (in km/h);

(3r-5) is the rate of the faster plane.


The total distance equation is  


    1.5r + 1.5*(3r-5) = 748.5   kilometers.


You do the rest.
