One approach is to treat this as a problem about PROPORTIONS.
When Karen finishes the 100-meter race, Jane is behind by .25 meters.
Thus, the distance traveled by Jane = 100 - .25 = 99.75 meters.
Since Jane give Karen a head start of 5 meters and finishes the race .25 meters behind Karen, Jane catches up by 5 - .25 = 4.75 meters.
Thus, for every 99.75 meters that Jane travels, she catches up by 4.75 meters.
To determine how much farther Jane must travel to catch up by another .25 meters, set up and solve the following proportion:
4.75 meters/99.75 meters = .25 meters/x meters
x = 5.25.
Thus, to catch up to Karen, Jane must travel another 5.25 meters.
