Homework Statement
A car travels along a straight line at a constant speed of 48.5 mi/h for distance d and then another distance d in the same direction at another constant speed. The average velocity for the entire trip is 30.5mi/h.
a) What is the constant speed with which the car moved during the second distance d?
Homework Equations
I know that speed = distance/ delta time, and that velocity = displacement/ delta time
The Attempt at a Solution
The only formula that I thought might help was Xfinal = Xinitial + (1/2)(Vxinitial + Vxfinal)time but then I decided that it was a dumb formula to use and now I'm stuck :/ I can't seem to relate the constant speed and average velocity to each other the right way..
Please help!
