A car moves at a speed of 55 km/h. How much distance will it cover in 12 minutes?

A. 9 km
B. 10 km
C. 11 km
D. 12 km
Correct Answer: C. 11 km
Explanation:


The correct answer is 11 km because we can find the distance by matching the time units to the speed format.



    • Step 1 (Convert Minutes to Hours): Since the speed is in kilometers per hour, convert 12 minutes into hours by dividing by 60:
      $$text{Time} = frac{12}{60} = frac{1}{5}text{ of an hour (or 0.2 hours)}$$

    • Step 2 (Calculate Distance): Multiply speed by time to find the total distance traveled:
      $$text{Distance} = 55 times frac{1}{5} = 11text{ km}$$

    • Incorrect Options:

      • 9 km, 10 km, and 12 km are incorrect values that do not match our distance equation.
