Question 638441: Can you please help me sove this problem? It is, "Matt traveled to his friends house and back. The trip there took 4 hours, the trip back took 6 hours. He averaged 20 mph faster on the trip there then on the trip back. Find his average speed on the out going trip."
I pulled out all the information that I could like what it's really asking and all the times and the mph. But then I got stuck. I've had problems with word problems for awhile but especially time and mixtures

"Matt traveled to his friends house and back. The trip there took 4 hours, the trip back took 6 hours. He averaged 20 mph faster on the trip there then on the trip back. Find his average speed on the out going trip.
**
let x=speed of outgoing trip
x-20=speed of trip back
distance=travel time*speed (same for outgoing and trip back))
..
4x=6(x-20)
4x=6x-120
2x=120
x=60
speed of outgoing trip=60 mph
