A freight train takes 1and 3/4 hours to get to the city;a passenger train averaging 64 mph faster takes only 75 mins to cover the shames distance. What is the average speed of the passenger train
Let the speed of the freigh train be x mph
so speed of the passenger train = (x+64) mph
75 minutes = 3/4 hours
x * 7/4 = (x+64) 3/4
7x = 3x+192
x = 48 mph
So so speed of the passenger train = (x+64) mph = 48+64 = 112 mph
