**bobpursley**, Sunday, May 24, 2009 at 2:07pmLEt v be the velocity of the turbo plane, then v-50 is the velocity of the slower. Let t be the time for turbo to go 2000 miles, then t+3 is the time for super .

(velocity*time)= distance

(v-50)(t+3)=2800

and

v*t=2000

From the second equation, t=2000/v, put that into the first equation.

(v-50)(2000/v + 3)=2800

multiply both sides by v

(v-50)(2000+3v)=2800v

multiply it all out, gather terms, and use the quadratic equation.
