38.71 mph
The idea is to divide the distance by the time. This will give you the AVERAGE speed for the trip, which may or may not have been the actual speed all the time.
1 knot = 1 nautocal mile per hour. So 428 nm @ 20 knots per hour will take 428/20 = 21.4 hours. After 12 hours, it is 20*12 = 240 nautical miles away. Its distance East is 240*cos(1.4deg) = 239.9 nautical miles and its distance South is 240*sin(1.4deg) = 5.9 nautical miles.
Just divide the distance by the time. The answer in this case will be in km/hour.
4 hours = 240 minutes.39/240reduces to13/80=====
If the car must overtake the bus in 5 hours and the bus left 3 hours before the car, then the bus has traveled for 8 hours = 240 km. The car needs an average speed of 240km / 5hr = 48 km/hr.
240/2.5 = 96 kph
The idea is to divide the distance by the time. This will give you the AVERAGE speed for the trip, which may or may not have been the actual speed all the time.

I think you mean if you drive at the same speed. Distance is then proportional to time. So 240 x 6/4.5 =240 x 4/3 =320 miles.
Average Speed = distance/time = 240/4 = 60 mph
At speed of 60 mph it is 4 hours At speed of 40 mph it is 6 hours and so on ...
Time = Distance / Speed So, it would take 240/60 = 4 hours
To work this out just divide the distance travelled by the time taken. In this case the answer is an average speed of 40kph.
Time = Distance / Speed = 240 / 48 = 5 hours.
if there's no traffic and are on the interstates, you could actually do about 400 miles in 6 hours and not break the speed of limit of 70 miles an hour
It depends on your travel speed. At ten miles per hour x 24 hours = 240 miles per day.
