Bike A completes a race in 10 minutes and 15 seconds whereas Bike B needs 11 minutes and 3 seconds to finish the same race. Which of the following claims about bike A and bike B's speeds is true?

• The object's speed determines its fast and slow motion.
• It is given as the distance covered per unit of time. 
  Speed= $\frac{\mathrm{Distance}}{\mathrm{Time}}$
• When an object is in slow motion, it takes more time to cover a distance whereas when the object is fast, it takes less time to cover the same distance.

Therefore, since bike A takes less time to finish the race than bike B, bike a must be faster than bike B.
