2022 AIME I Problem 5


A straight river that is 264264 meters wide flows from west to east at a rate of 1414 meters per minute. Melanie and Sherry sit on the south bank of the river with Melanie a distance of DD meters downstream from Sherry. Relative to the water, Melanie swims at 8080 meters per minute, and Sherry swims at 6060 meters per minute. At the same time, Melanie and Sherry begin swimming in straight lines to a point on the north bank of the river that is equidistant from their starting positions. The two women arrive at this point simultaneously. Find DD.
Leading zeroes must be inputted, so if your answer is 34, then input 034
