Two cars leave towns 230 km apart at the same time, traveling towards one another. One car travels 15 km slower than the other. They meet 2 hours later. What are their speeds?

Call the faster cars rate V, then the slower car travels V-15 km/hr

together they travel 2V-15 km/hr
so...




and simplifying we get V=65 km/hr
(and so the slower car travels 50 km/hr)
