Two bugs, one fast and one slow, are running back and forth along the entire length of a straight branch. They start from opposite ends of the branch at the same time, and each one travels at a constant speed. The bugs meet for the first time at 40 cm from one end of the branch. They continue to the opposite ends and return, meeting for the second time 20 cm from the other end of the branch. How long is the branch? Can you please tell me the answer and show the work??? PLS!!! THANKS!!!
