In a 100 m sprint race Kelly was given a 3 m head start by Abel. If Abel lost the race to Kelly by a distance of 0.50 m, how many meters more would Abel need to overtake Kelly?	Choices.
A) 20.5  B) 18.4  C) 17.5  D) 19.9  E) 21.5
Distance Abel ran before completion of race---100 m-0.50m=99.5m   Distance gained on Kelly over 99.5m---3m-0.50m=2.50m   then Abel gains 99.5m/2.50m = 1m on Kelly every 39.8 meters.   Therefore 39.8 divided by half a meter ( i.e the 0.50 m Abel was defeated with)   ANSWER: D. 19.9m
