Decide whether the statement makes sense. Explain your reasoning.I drove really far, almost 200 kilometers per hour.

What will be an ideal response?


Does not make sense. Kilometers per hour are a unit of speed, not distance. If you drive fast but only for a short period of time, you will not go far. (Explanations will vary.)
