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
