    10 Km.

    S = Speed

    D = distance

    T = time

    S = d/t

    but since you are solving for "d" the equation is d=st so you plug in 10 km/h for speed and 2.1 hours for time and just multiply them. The hours cancel out so you are left with 10km.

    Um I think you need to multiply 10 km by 2.1
