Divide 240 by 6 and you will get the answer. ie how many km travelled in 1 hour
240/2.5 = 96 kph
38.71 mph
sixty
60 KPH
To work this out just divide the distance travelled by the time taken. In this case the answer is an average speed of 40kph.
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.
37mph or 60kph
240divided by 4 = 60 kph
60 kph, which is derived from taking the 240 kilometers it has travelled total and dividing by the four hours it took to traverse said distance.
30 kph
Difference in distance covered = (240 - 180) = 60 kmBut since speeds differ by 20 kph, difference in distance is (20 x #hours).60 = 20 x #hours#hours = 60/20 = 3 hours.Fast car covers 240 in 3 hours ---> 80 kphSlow car covers 180 in 3 hours ---> 60 kph
The passenger train is going 56 mph, and the freight train is going 48 mph. The time they take to reach 280 and 240, respectively, is 5 hours.
