Two ants A and B start from a point P on a circle at the same time, with A moving clock-wise and B moving anti-clockwise. They meet for the first time at 10 00 am when A has covered 60 of the track. If A returns to P at 10 12 am, then B returns to P at

Accepted Answer

Step 1 Let total length of the circular track be L. At 10 00 am, they meet when A has covered 60 of the track 0.6L So B must have covered 0.4L since they started from same point and moved in opposite directions Step 2 Let speeds of A and B be v and v Since both covered 0.6L and 0.4L in the same time
