Question

A cyclist starts from the centre O of a circular track of radius 1 km, reaches the edge A of the track and then cycles along the circumference and stops at point B as shown in the figure. If the total time taken is 10 min, what is the average velocity of the cyclist ?

• A. 3 km/hr
• B. 6 km/hr
• C. 9 km/hr
• D. 12 lm/hr

Answer 1

Answer: (B)

6 km/hr

Answer 2

$V_{avg} = \frac{displacement}{time} = \frac{1000}{10 \times 60} \times \frac{18}{5}$
