Answer:
(Need distance from each other to find out)
Step-by-step explanation:
Speed of particle one: (97-4(n-1)) cm/2s (n=how many two seconds are there)
Speed of particle two: (49-2(n-1)) cm/2s
distance / (speed of particle one + speed of particle two) = time of meet
then use time & plug in each to find out distance travelled by each
