Question: A swimmer swims 200 meters in 2 minutes. What is his speed in kilometers per hour? (2021)

Options:

Correct Answer: 6 km/h

Exam Year: 2021

Solution:

Speed = Distance / Time = 200 meters / 120 seconds = 1.67 m/s. To convert to km/h, multiply by 3.6: 1.67 * 3.6 = 6 km/h.

A swimmer swims 200 meters in 2 minutes. What is his speed in kilometers per hour? (2021)

Step 1: Identify the distance the swimmer swam, which is 200 meters.
Step 2: Identify the time it took the swimmer to swim that distance, which is 2 minutes.
Step 3: Convert the time from minutes to seconds. Since 1 minute is 60 seconds, 2 minutes is 2 * 60 = 120 seconds.
Step 4: Calculate the speed in meters per second (m/s) using the formula: Speed = Distance / Time. So, Speed = 200 meters / 120 seconds.
Step 5: Perform the division: 200 / 120 = 1.67 m/s (approximately).
Step 6: To convert the speed from meters per second to kilometers per hour, multiply by 3.6. So, 1.67 m/s * 3.6 = 6 km/h.
Step 7: The final speed of the swimmer is 6 kilometers per hour.

Speed Calculation – Understanding how to calculate speed using the formula Speed = Distance / Time.
Unit Conversion – Converting speed from meters per second (m/s) to kilometers per hour (km/h) using the conversion factor of 3.6.
