Question: A river flows at a speed of 2 m/s. How far will it flow in 3 hours?

Options:

Correct Answer: 21600 m

Solution:

2 m/s * 3600 seconds/hour * 3 hours = 21600 m

A river flows at a speed of 2 m/s. How far will it flow in 3 hours?

A river flows at a speed of 2 m/s. How far will it flow in 3 hours?

Step 1: Understand the speed of the river, which is 2 meters per second (m/s).
Step 2: Convert the time from hours to seconds. There are 3600 seconds in 1 hour.
Step 3: Since we have 3 hours, multiply 3 hours by 3600 seconds/hour to get the total seconds: 3 * 3600 = 10800 seconds.
Step 4: Now, use the formula: Distance = Speed * Time.
Step 5: Substitute the values into the formula: Distance = 2 m/s * 10800 seconds.
Step 6: Calculate the distance: 2 * 10800 = 21600 meters.
