    ((5 cm/50 km) + (x/50 km)) * 100 m = .00004 m/s

    Re: help with algebra problem

    The first thing to do is get your units right: you have only metres and units of length on the left hand side but you have metres per second on the right hand side.

    Something is wrong and I'm guessing it's on the left hand side. You can't continue unless you get a balance of the right units on both sides of the equation.
