A 100m race is won by 0.01s. What distance separated the 1st and 2nd place runners at the finish line if the winner finished with a time of 10.07s?
Given:
The total distance travelled by all the runners is 100m The time taken t cover 100m by the 1st winner is 10.07 s Now, the time taken by the 2nd winner will be (10.07 0.01) 10.08 s
Speed of the 2nd...
Distance travelled 100 Thus, the speed of the 2nd winner = 9.9206 m /s Time taken 10.08
