Average speed = Distance/Time = 400 km /5 hours = 80 km per 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.
Kilometers measure distance; hours measure time- you can not convert distance to time. its just silly to try to convert measurement to time.
400/5 = 80. HBD!
400 ÷ 20 = 20 hours (though it is unlikely that the speed would be constant!)
Average speed = Distance/Time = 400 km /5 hours = 80 km per 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.
The relationship between 400 kilometers and 8 hours is the speed at which distance is covered, which is 50 kilometers per hour. This can be calculated by dividing the total distance by the total time taken.
The speed appears to be 400 miles an hour. If you meant 400 miles, the speed is 50 miles an hour.
A train that travels at 40 kilometers per hour (kph) for 10 hours goes 400 kilometers. If the train goes 50 kph for 8 hours, it also travels the same 400 kilometers. The difference in speeds is 10 kph, and the difference in times is 2 hours.
Kilometers measure distance; hours measure time- you can not convert distance to time. its just silly to try to convert measurement to time.
About 7 hours with 400 miles or 643 kilometers.
around 400 Km / 3-4 hours
To calculate the time it would take to travel 400 km at a speed of 80 km per hour, you would divide the total distance by the speed. So, 400 km divided by 80 km per hour equals 5 hours. Therefore, it would take 5 hours to travel 400 km at a speed of 80 km per hour.

400/5 = 80. HBD!
There are 40,000,000 centimeters in 400 kilometers, as there are 100,000 centimeters in a kilometer.
