Question 92673: Mike and Adam left a bus terminal at the same time and traveled in opposite directions. Mike's bus was in heavy traffic and had to travel 20mi/h slower than Adam's bus. After 3 hours, their buses were 270 miles apart. How fast was each bus going?
It's the after 3hrs that confuse me. Can you help?

You can put this solution on YOUR website! 270=3*X+3(X-20) MILEAGE=R*T+R*T.
270=3X+3X-60
6X=270+60
6X=330
X=330/6
X=55 MPH FOR ADAM'S SPEED.
55-20=35 MPH FOR MIKE'S SPEED.
PROOF'270=3*55+3*35
270=165+105
270=270
