a circular track having length 4300m.there r 3 players saniya,paducone and gopi.all r standing diametrically.saniya and paducone standing opposite to each other.gopi standing exact mid of saniya and paducone.the speed of saniya,gopi and paducone are 5m/sec,10m/sec and 8m/sec.they start running at 10am.gopi and paducone r running clockwise direction and saniya anticlockwise.how much distance covered by gopi?when saniya and paducone meet first time after 10:05am.

• speed of G =10m/sec and 10.05-10.00=5 mins= 5*60=300 secs.....Now d=st ⇒d= 300*10= 3000 m....
  speed of S= 5m/sec and P=8m/sec
  Relative Speed=8+5=13
  t=4300/13=330 as [13*33=429]
  Now 5mins=300secs..That means this 330secs is more than 10.05...Then S and P shall meet at 330secs ..ie after 10.5
