Constant Speed Problem
hey, i am gonna just write the problem just as it is in the textbook. I have thought about this one for a while, and yet have no idea where to start. I figured out the answer (I think) by guess and check, but i would really like to UNDERSTAND why the answer is what it is. Thanks, here it is:
Two runners approaching each other on a straight track have constant speeds of 4.50m/s and 3.50m/s, respectively, when they are 100m apart. How long will it take for the runners to meet, and at what position will they meet if they maintain these speeds?
It kinds looks like so:
Runner A 4.5m/s>>>______________100m______________<<<Runner B 3.5m/s
