A bucket is set at the starting line, which is 5 meters from the first potato, and the other potatoes are arranged in a straight line, 3 meters apart. Ten potatoes are in the line. A competitor starts from the bucket, picks up the nearest potato, runs back with it, drops it in the bucket, runs back to pick up the next potato, runs to the bucket to drop it in, and he continues in the same way until all the potatoes are in the bucket. What should be the total distance the competitor has to run?
