To calculate the average speed in km per hour, we need to convert the distance from meters to kilometers and the time from seconds to hours.

Distance: 90 meters = 0.09 kilometers (there are 1000 meters in a kilometer).
Time: 10 seconds = 0.00278 hours (there are 3600 seconds in an hour).

Now, divide the distance by the time to calculate average speed:

Average speed = Distance / Time
Average speed = 0.09 km / 0.00278 hours
Average speed ≈ 32.37 km/h

Therefore, the boy's average speed is approximately 32.37 km/h.
