Problem Statement

In three houses A,BA,B and CC, forming a right triangle with the legs AC=30AC=30 and CB=40CB=40, live three beetles a,ba,b and cc, capable of moving at speeds of 2,32, 3 and 44, respectively. Suppose that you simultaneously release these bugs from point MM and mark the time after which beetles reach their homes. Find on the plane such a point MM, where is the last time to reach the house a bug would be minimal.
