At a 10,000 m race, The Flash starts first and is followed later by Bolt. The speed of Bolt is 1 m/s more than that of The Flash’s. When Bolt catches up with The Flash, The Flash increases his speed by 2 m/s, while that of Bolt remains unchanged. As a result, Bolt finishes 7 min 8 s after The Flash. If the distance had been 500 m more, then Bolt would have finished 7 min 33 s after The Flash. The time gap between the start of The Flash and Bolt is a. 2 min b. 2.5 min c. 3 min d. 1 min
