To convert kilometers to hours, you need to know the speed at which the distance is being covered. If you are traveling at a speed of 80 kilometers per hour, for example, then you would divide the distance (400 kilometers) by the speed (80 kilometers per hour) to find that it would take 5 hours to cover that distance. So, in this case, 400 kilometers would be equivalent to 5 hours of travel time at a speed of 80 kilometers per hour.

Kilometers measure distance; hours measure time- you can not convert distance to time. its just silly to try to convert measurement to time.
a) Divide the kilometers by the hours, to get the speed in kilometers per hour. b) Divide this result by 3.6, to convert to meters/second.
You cannot convert 400 meters to 3 kilometers. They are two different lengths. 1 kilometer = 1,000 meters. 3 kilometers would be 3,000 meters. 400 meters would be 0.4 kilometers
0.4 km
Average speed = Distance/Time = 400 km /5 hours = 80 km per hour.
You can't. Units of time don't convert to units of distance.
