On a particular day they each left their respective homes at the exact same time and jogged toward each other but at different paces. When they passed each other for the first time, they happened to be exactly 700 yards from Dave’s home.Each continued jogging at a constant pace to the opposite friend’s home, then, turned around and jogged back toward each other again. When they passed for the second time, they were exactly 300 yards from Rob’s home.
