Question
What was the speed of a person who ran 10 meters in 2 seconds?A 0.2 m/sB 5 m/sC 8 m/sD 20 m/s
Solution
The speed of a person can be calculated using the formula: speed = distance/time.
Step 1: Identify the distance and time from the question. The distance is 10 meters and the time is 2 seconds.
Step 2: Substitute the distance and time into the formula. So, speed = 10 meters / 2 seconds.
Step 3: Calculate the speed. The speed is 5 meters per second.
So, the correct answer is B. 5 m/s.
