Question: A person runs 5 km in 25 minutes. What is their speed in km/h?

Options:

Correct Answer: 12 km/h

Solution:

Speed = Distance / Time = 5 km / (25/60) h = 12 km/h.

A person runs 5 km in 25 minutes. What is their speed in km/h?

A person runs 5 km in 25 minutes. What is their speed in km/h?

Step 1: Identify the distance run, which is 5 km.
Step 2: Identify the time taken, which is 25 minutes.
Step 3: Convert the time from minutes to hours. Since there are 60 minutes in an hour, divide 25 by 60. This gives you 25/60 hours.
Step 4: Use the formula for speed, which is Speed = Distance / Time.
Step 5: Substitute the values into the formula: Speed = 5 km / (25/60) h.
Step 6: Simplify the calculation. To divide by a fraction, multiply by its reciprocal: Speed = 5 km * (60/25).
Step 7: Calculate the result: 5 * 60 = 300, and 300 / 25 = 12.
Step 8: Therefore, the speed is 12 km/h.
