A pre-timed four phase signal has critical lane flow rate for the first three phases as $200$, $187$ and $210$ veh/hr with saturation flow rate of $1800$ veh/hr/lane for al phases. The lost time is given as $4$ seconds for each phase. If the cycle length is $60$ seconds, the effective green time (in seconds) of the fourth phase is ________

A student riding a bicycle on a $5$ km one-way street takes $40$ minutes to reach home. The student stopped for $15$ minutes during this ride. $60$ vehicles overtook the student (assume the number of vehicles overtaken by the student is zero) during the ride and $45$ vehicles while the student stopped. The speed of vehicle stream on that road (in km/hr) is $7.5$ $12$ $40$ $60$
