First person's speed is 1/30
and second one's is 1/20.
So, (1/20 + 1/30)×X =1
5/60*x=1
X=60/5=12
That is they meet each other first time, after 12 minutes.
9:30-8=1:30 or 90 minutes
90÷12=~7

Assume the perimeter of the track=x
Speed of first person= \(\frac{2*x}{1}\)=2x
Speed of second person= \(\frac{3*x}{1}\)=3x
Time taken by them to meet first time=\(\frac{x}{(2x+3x)}\)=\(\frac{1}{5}\) hrs= 12 minutes
Number of times they cross each other before 9:30AM= [\(\frac{1.5*60}{12}\)]=[7.5]=7
