Final answer:

Kyle's average speed is calculated by dividing the distance traveled (1/2 km) by the time traveled (1/6 hour) resulting in an average speed of 3 km/h.

Step-by-step explanation:

The student has asked for the calculation of Kyle's average speed in kilometers per hour when he walks 1/2 km in 10 minutes.

To find the average speed, we use the formula: distance traveled divided by the time of travel.

  1. Firstly, we know Kyle walks 1/2 km in 10 minutes.
  2. Since there are 60 minutes in an hour, we convert 10 minutes to hours by dividing 10 by 60, which gives us 1/6 hour.
  3. Now, we calculate the average speed by dividing the distance (1/2 km) by the time (1/6 hour), which equals 3 km/h.

Therefore, Kyle's average speed is 3 km/h (Option A), which is a reasonable speed for walking.
