Q
Q: If a person runs 10 km in 40 minutes, what is his speed in km/h? (2021)
Solution:
Speed = Distance / Time = 10 km / (40/60) hours = 10 / (2/3) = 15 km/h.
Steps: 7
Show Steps
Step 1: Identify the distance run, which is 10 km.
Step 2: Identify the time taken, which is 40 minutes.
Step 3: Convert the time from minutes to hours. Since there are 60 minutes in an hour, divide 40 by 60. This gives you 40/60 = 2/3 hours.
Step 4: Use the formula for speed, which is Speed = Distance / Time.
Step 5: Substitute the values into the formula: Speed = 10 km / (2/3) hours.
Step 6: To divide by a fraction, multiply by its reciprocal. So, Speed = 10 km * (3/2).
Step 7: Calculate the speed: 10 * 3 = 30, and then divide by 2, which gives you 15 km/h.
