Questions & Step-by-Step Solutions
A river has a width of 300 meters. If a boat crosses the river at a speed of 15 m/s, how long will it take to cross the river? (2020)
Step 1: Identify the width of the river, which is 300 meters.
Step 2: Identify the speed of the boat, which is 15 meters per second.
Step 3: Use the formula for time, which is Time = Width / Speed.
Step 4: Plug in the values: Time = 300 meters / 15 meters per second.
Step 5: Calculate the result: 300 divided by 15 equals 20.
Step 6: Conclude that it will take the boat 20 seconds to cross the river.
