75 miles x miles
------------ = --------------
60 minutes 40 minutes
75*40 = x*60
3000 = 60x
50 = x or 50 miles

40 minutes / 60 minutes/hour x 75 miles per hour
40/60 x 75 = 2/3 x 75 = 50 miles

75 mph X 40 min / 60 min per hr = 50 miles

Distance = velocity * time
It's important that you keep all your units consistent in these equations - you want to know distance after a number of minutes, but your velocity is given in in terms of hours - easy - convert your time to a fraction of an hour (40 min = 2/3 hour).
So
distance = 75 mph * 2/3 hour = 50 miles :)

75 x
---- = -------
60 40
75(40)=60x
3000=60x
50=x
the train will be traveling at 50 mph
