Question
the barge travels upstream 75.5 miles to the factory and then back to the warehouse.the barge travels upstream at a rate of 5 miles per hour slower than it travels downstream.the barge total time is 15 hours.what is the rate the barge travels downstream

If the downstream rate is x, then since time = distance/speed,
75.5/x + 75.5/(x-5) = 15
75.5/x + 75.5/(x-5) = 15
