    55 meters per second. Use 1 kmph=0.27 mps Distance traveled in 10 seconds = 55 x 10 = 550 meters

    \[198\,[\text{km/hr}]\\ =198\,[\text{km/hr}]\times1\times 1\\ =198\,[\text{km/hr}]\times\frac{[\text{hr}]}{3600\,[\text s]}\times\frac{1000\,[\text m]}{[\text{km}]}\\ =\]

    \[=\left(198\times\frac1{3600}\times 1000\right)\,[\text{m/s}]\\ =\]

    for the second part of the question, use \[v = d/t\] (solve for \(d\))
