"Mile" is a distance, but "kilometers per hour" is a speed.
You can't directly convert one to the other.
3 miles = 4.828 kilometers
3 miles per hour = 4.828 kilometers per hour
32 kph = about 17.3 knots. (17.2786177 knots)
3 kph is a measurement of speed or velocity. Maintaining this speed for one hour will cover 3 kilometers.
The question needs to be more specific.
Average of what? People walking, traffic on an motorway, combat aircraft in action, bricks in a building, etc.
Between 30 & 35 kph
