George while driving along the highway saw road markers which are at equal distances from each other. He crosses the markers every 20 seconds. If he increases his speed by x meters per second, he crosses the markers at every 15 seconds. But if he increases his speed by y meters per second, he crosses the marker at every 10th second. If y-x = 40 meters per second, then what is the distance between two markers.

Samuel is obviously a bad fisherman. During the past season, in which he and the five members of his team spent four months on a boat together off Dutch Harbor, AK, he caught fewer fish than any of his teammates. Which of the following, if true, most weakens the argument above? While fishing this past season, Samuel fell sick for a week and did not catch any fish during this time. Before becoming a fisherman, Samuel piloted a fishing boat whose members regularly caught record numbers of fish. Unlike the other fishermen on his boat, at the order of the captain, Samuel fished this past season with experimental bait. Two seasons ago, Samuel fished on another boat off Dutch Harbor and caught more fish than any other member of that boat.
