On the number line, a slow bug s and a fast bug f are moving in the positive direction from the point 0. the speeds of both bugs are constant. both leave 0 at the same time, and four seconds later f has reached 12 and s has reached 8. 30 seconds after leaving point 0, how far apart are f and s ? units when will f and s be 100 units apart? seconds , don't write a whole bunch of nonsense for the points and answer all the ! i !
