    Relating change in time to change in position and velocity

    I was looking back at some homework solutions I've solved earlier this term and I ran across this equation: Δt = 2*Δx/(vf+vi) Which seems to translate to: Δt = Δx/vave Is this an actual way of finding delta t? I got the answer right, but I can not understand or find where I got this...
