Q: A soldier runs 12 km in 1 hour and 15 minutes. What is his speed in km/h? (2023)

Step 1: Convert the time from hours and minutes to just hours. 1 hour and 15 minutes is the same as 1.25 hours.
Step 2: Use the formula for speed, which is Speed = Distance / Time.
Step 3: Plug in the values: Distance is 12 km and Time is 1.25 hours.
Step 4: Calculate the speed: 12 km divided by 1.25 hours equals 9.6 km/h.
