a. 450 m
b. 680 m
c. 700 m
d. 900 m
e. 1000 m

ANSWER: 700 m
 
When Sanket finishes the race in 15 minutes, Suresh & Sam would finish the same race in 5 minutes and 2.5 minutes respectively. Thus, when Sam reaches the ”finish” mark, Suresh must be “half-way” through i.e. 700 meters behind the “finish” line when “Sam” must have finished the race.
