- 2600 m
when they first met 900m cw from the starting pt.
second time, they will meet at 1800 m cw from starting point which is 800 m CCW from starting point.
so circumference of circle = 1800+800 = 2600 m - 12 years agoHelpfull: Yes(1) No(1)
- 1000 m
bcoz the persons r runnin at const. rate. one of the two is runnin 100 m bw d 1st nd d 2nd meet. so he might ve run 100 m b4 d 1st meet also. so d circumference is 900 meter(cw) + 100 meter(acw) = 1000 meter - 12 years agoHelpfull: Yes(0) No(1)
