I must assume that you typed your question carelessly, and that instead of
minute/second, you actually intended mile/second.
(Q mile/second) x (0.62137 kilometer/mile) x (3,600 second/hour) = 2,236.94 Q kilometer/hour

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.
(P meter/second) x (1 kilometer/1,000 meters) x (3,600 second/hour) = 3.6 P kilometer/hour
As we know that 1 hour consists of 60 minutesso, 1 minute would be of 1/60 hours (or 0.0166666666666667 hours approximately)Thus, 0.7 kilometers/minute can be written as0.7 kilometers/0.0166666666666667 hourswhich, on simplification (calculation) gives 42 kilometers per hour.Result42 kilometers per hour
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.
There are 60 minutes in an hour. There are 60 seconds in a minute. There are 1000 milliseconds in a second. Multiply: 60*60*1000 Answer: 3600000 There are 3600000 milliseconds per hour. Multiply this by the number of hours you want to convert. If you wish to convert milliseconds to hours (the other way around), you need to divide by 3600000.
