In a 1200 m race, bike A beats bike B by 100 m. Bike B beats bike C by 100 m in a 600 m race. If bike A beats bike C by 30 sec in a 720 m race, then what is the speed of bike C?

A. $$\frac{{17}}{3}{\text{ m/sec}}$$

B. $$\frac{{26}}{9}{\text{ m/sec}}$$

C. $$\frac{{17}}{9}{\text{ m/sec}}$$

D. $$\frac{{26}}{3}{\text{ m/sec}}$$

Answer: Option A

Solution (By Examveda Team)

\[\begin{array}{*{20}{c}} {\text{B}}&{\text{C}} \\ {600}&{500} \\ {600\,{\text{m}}}&{{\text{Race}}} \end{array}\]
$${\text{Speed}} = \frac{{170}}{{30}} = \frac{{17}}{3}{\text{m/s}}$$
