Question 557673: Pete and his family take a trip out into the country by car. On the way out he travels at 40 MPH . When they hit snow he turned around and started back traveling at 30 MPH. If the entire trip took 7 hours, how far out into the country did they go?
I tried 40x + 30x = 7(60)
But that is not the correct answer.
if you could help me that would be great

Question 558130: A passenger plane flew to moscow and back. The trip there took five hours and the trip back took nine hours. It averaged 144 km/h faster on the trip there than on the return trip. Find the passenger plane's average speed on the outbound trip.
O.k so I did have a go at it Trying to use a system of equations using the substitution method to eliminate one unknown but it didn't work. I will try and explain what I was playing around with:
D1 = Distance there D2 = Distance back ( but not sure if I needed this as it is same Distance )
Average Speed = S
D1/5 + D2/9 = S
D1/5 = D2/9+144 ( I tried substituting this in )
D2/9+144 + D2/9 = S ( then I combined the like terms )
D2/18+144 = s ( but this is where I realized I had failed as I still had 2 variables.
Please help me someone I am so bad at word problems and I would love to be confident at them.
P.S I wasn't sure about which was the outbound trip, I guessed it meant the trip back.
