Question 214838: Car A is traveling at 20 miles per hour. Car B is one mile behind, following at 30 miles per hour. A fly can move 40 miles per hour. The fly begins on the front bumper of car B and flys back and forth between the two cars. How many miles will the fly travel before it is crushed in the collision?
Totally confused as to how to set it up. I know

Question 214899: This question I come up with the wrong answer:
Pete drove from Buffalo to Boston, a distance of 720km. On return trip he increased his speed by 10km/h. If the total trip took 17h, what was his speed from Boston to Buffalo?
I'm having trouble working it out, I begin with this:
I start with (720/x)+(720/x+10)
Expanded it to: 17x^2 - 1270x + 7200
Speed I got next using the quadratic equation: 62.5
But thats apparently wrong, what am I doing wrong?
