If one's speed changes from 10 km/h to 6 km/h, one has decelerated.

That depends upon the speed of sound through the medium in which the speed is being measured. mach = speed ÷ speed_of_sound_there ⇒ speed = mach x speed_of_sound_there In dry air at 20oC the speed of sound is [approx] 1236 km/h ⇒ speed_of_mach_0.85 = 0.85 x 1236 km/h ≈ 1051 km/h At 11,000m (where the air temperature is about -50oC) the speed of sound is approx 86% of that in air at 20oC, that is about 1063 km/h ⇒ speed_of_mach_0.85 ≈ 0.85 x 1063 km/h ≈ 904 km/h
speed = distance / time330 km / 8 h = 41.25 km/h (kilometres per hour)

The average speed of the car = 300 [km] / 5.5 [h] = 54.55 [km/h]. ==========================
The typical speed limits in most Canadian provinces are 50 km/h in cities, 80 km/h outside of cities, and 100 km/h on freeways. School zones usually have a speed limit of 30 to 40 km/h in cities and 50 km/h outside of cities.
Top speed of the 170cc bike is approx. 140 km/h to 150 km/h.

Is what the speed of light or light speed.ANSWER300,000 km/s
An object moving in a straight line at a speed of 50 km/h with a constant velocity of 50 km/h in the same direction is an example of constant speed and constant velocity.
The fish's average speed is 2 km/h, as distance divided by time gives you the speed which is 20 km / 10 hours = 2 km/h.
