    It would be hard to climb because an is steeper

  32. jim_thompson5910

    since B is steeper, it has a larger slope, which basically means B is moving faster than A

    B is going faster because B is walking up the escalator so would C go faster than B? or slower than B? and why?

    Faster because the lines are Steep

    is C on the stairs? or on the escalator?

    so C will be moving slower than B but faster than A this is assuming that the escalator is moving relatively fast and A is walking up the stairs slowly

    so we'd expect C to be somewhere in the middle in terms of slope can you draw for me what line C could look like?

    C is steeper than A, which means C is faster than A (because C is on an escalator and A is on the stairs) B is steeper than C, so B is faster than C (because B is walking while C is still)
