A pedestrian team sets off at a constant speed of $5 \mathrm{~km/h}$. A bicycle messenger starts 4 hours and 24 minutes later. After travelling $8 \mathrm{~km}$, the cyclist's inner tube bursts. It takes 10 minutes to change the tube. Then, going at a speed which is $2 \mathrm{k}m/h$ faster, the messenger catches up with the team at the same spot, as if he had continued without stopping at the initial speed. What is the initial speed of the cyclist?
