You can use the rate equation to solve for the time it will take the train to cover the distance. Your answer will be in hours because the given rate is in kilometers per hour. Let t stand for the total time of the trip:
R*T=D
240*T=420
T=7/4
(Note that you can omit the units in your calculation if you verify ahead of time that you are dealing with a consistent system of units.) Finally, convert the time from hours into minutes:
7/4*60=105 minutes
B > A
