The answer will depend on whether you took 5.8333333 seconds, hours, days, years. And since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.
Per hour the answer is 400 watt-hours or 0.4 kW-hours (or units).
400 mph
The Great Red Spot on Jupiter spins at a speed of around 400 kilometers per hour (about 250 miles per hour). It completes one rotation in about six Earth days.
400 mph.
Directly, there is no relationship. A kilometre is a measure of distance, an hour is a measure of time. There may be a relationship if there were some information on speed or, at the very least, mode of transport.
The speed appears to be 400 miles an hour. If you meant 400 miles, the speed is 50 miles an hour.
Speed is calculated by the division of distance by time taken. I took 400km so I will divide it by the time I took, that is, 5.8333333 and get a speed of 68.57147 km/h.
400 miles per hour
Average speed = Distance/Time = 400 km /5 hours = 80 km per hour.
400 meters in 43.18 seconds equates to an average speed of 20.72 miles per hour.
