Q
Q: In a swimming competition, a swimmer completes a lap of 50 meters in 30 seconds. What is the swimmer's speed in meters per second? (2022)
Solution:
Speed = distance/time = 50 m / 30 s = 1.67 m/s, which rounds to approximately 2 m/s.
Steps: 6
Show Steps
Step 1: Identify the distance of the lap. The distance is 50 meters.
Step 2: Identify the time taken to complete the lap. The time is 30 seconds.
Step 3: Use the formula for speed, which is Speed = Distance / Time.
Step 4: Plug in the values: Speed = 50 meters / 30 seconds.
Step 5: Calculate the speed: 50 divided by 30 equals approximately 1.67.
Step 6: Round the speed to the nearest whole number if needed. 1.67 rounds to approximately 2.
