A stream flows at a rate of 3 kilometers per hour. About that can travel at 15 kilometers per hour in still water start upstream. How long will it take the boat to travel 36 kilometers upstream
Answer (1)
Answer:Here's how to solve this problem: 1. Calculate the boat's speed upstream:The boat's speed in still water is 15 km/h.The stream's speed is 3 km/h.The boat's speed upstream is 15 km/h - 3 km/h = 12 km/h. 2. Calculate the time to travel upstream:Distance = 36 kmSpeed = 12 km/hTime = Distance / Speed = 36 km / 12 km/h = 3 hours Therefore, it will take the boat 3 hours to travel 36 kilometers upstream.
