So far these are the equations I have gotten:

Distance1 + Distance2= 300miles

rate1(time1) + rate2(time2)= 300 miles

rate1= rate2 + 20 mph

time1 + time2 = 6 hrs

However I cant combine them into one equation...

How would you do that

(X+20) mi/h = Speed of #2.

d1 + d2 = 300 Miles.

6x + 6(x+20) = 300

6x + 6x+ 120 = 300

12x = 300 - 120 = 180

X = 15 mi/h.

X+20 = 15 + 20 = 35 mi/h.
