Barbara, mark, and carlos participated in the third heat of “the big race”. barbara thought she could win with a 3 meter head start even though she only pedaled 3 meters every 2 seconds. mark began at the starting line and finished the 20-meter race in 5 seconds. meanwhile, carlos rode his tricycle so that his distance (y) from the starting line in meters could be represented by the equation y = x + 1, where x represents time in seconds. who would win in a 20 meter race?
