Two cars A and B drive straight towards the same point P with speeds a and b respectively. At the start, A, B and P form an equilateral triangle. After some time A and B move to the new positions, B covers 80 miles, and ABP becomes a right triangle. At the moment when A arrives at P, B is 120 miles away from P. What is the distance between A and B in the beginning?

• distance between A and B in the beginning is 240 kms.
  
  Let others try.
  I shall give sol later if correct.

• Answer is 240 kms...just that as A is moving faster...triangle BAP would become a right triangle... then using cos(60), just make two eqs and solve
