Answer 2

I think you have to express the speed from Km/hr to m/s. In order to that, please you have to divide the speed measured in Km/hr by the factor 3.6, so that speed will result measured in m/s. So:
\[\frac{ 320 }{ 3.6 }=...\]
please calculate the right quotient and write your answer, so I can go to next step
