Two cars $ P $ and $ Q $ are moving in a racing track continuously for two hours. Assume that no other vehicles are using the track during this time. The expressions relating the distance travelled d (in km) and time t (in hour) for both the vehicles are given as

$ \begin{array}{l}P:\;d=60\;t\\Q:\;d=60\;t^2\end{array} $

Within the first one hour, the maximum space headway would be

In a one-lane one-way homogeneous traffic stream, the observed average headway is 3.0 s. The flow (expressed in vehicles/hr) in this traffic stream is________
