In a controlled braking test, a cyclist is riding at 27 km/h when a hazard appears. The cyclist's reaction time is 0.40 s and the stopping distance is 13 m. A speed of 1 m/s is equivalent to 3.6 km/h. What is the braking distance?
3 m3\ \mathrm{m}3 m
10 m10\ \mathrm{m}10 m
16 m16\ \mathrm{m}16 m
2.2 m2.2\ \mathrm{m}2.2 m
