A cyclist covers 500 m in 5 minutes. What distance (in km) would the cyclist cover in half an hour if he travels at the same speed ?
Given that a cyclist covers a distance of 500 m in 5 minutes (300 sec) then speed of the cyclist is given by,
s = $$\frac{500}{5 \times 60}$$
s = $$\frac{5}{3}$$
Total distance the cyclist would cover in half an hour (1800 sec) if he travels at the same speed is given by,
d =Â $$\frac{5}{3} \times 1800 $$ m
d = 3000 m (or) 3km
Hence, option B is the correct answer.
