Anne, Bet, and Corr are three bees that start from the same flower and fly away in three different directions in search of nectar. After some time Corr is as distant from the mid point ‘D’ of the straight line joining Anne and Bet as Anne is from D. Anne and Bet are 300 m apart while Bet is 180 m from Corr.
