Q
Q: A river flows at a speed of 3 m/s. How far will it travel in 2 hours? (2020)
Solution: Distance = speed × time = 3 m/s × 7200 s = 21600 m.
Steps: 5
Step 1: Identify the speed of the river, which is 3 meters per second (m/s).
Step 2: Convert the time from hours to seconds. Since there are 3600 seconds in an hour, multiply 2 hours by 3600 seconds/hour: 2 hours × 3600 seconds/hour = 7200 seconds.
Step 3: Use the formula for distance, which is Distance = speed × time.
Step 4: Plug in the values: Distance = 3 m/s × 7200 s.
