    You had to measure the scale. It was 4cm so:
    4x10=40
    40/0.1=400

    I'm pretty sure it was that

    0.1mm (scale) = 4cm

    4cm = 40mm

    40/0.1 = 400

    Anyone else get this for magnification?
    I got this too

    For the 5 marker what did u lot put?
    I put something along the lines of Runner 1 had more heartbeats so more oxygen more aerobic respiration which helps the muscles contact. He also had more blood flow so this removed more lactic acid which prevented anaerobic respiration
