Rate*Time=Distance
Freight train is train 1, passenger train is train 2.
R1%2AT1=D
R2%2AT2=D
Both go to the same destination, travel the same distance.
R2=18%2BR1
Train 2 is 18 mph faster than Train 1.
T1=4.2
T2=3
Train 2 takes 3 hours, train 1 1.2 hours longer.
R1%2A4.2=%2818%2BR1%293
4.2R1=54%2B3R1
1.2R1=54
R1=45mph
R2=45%2B18=63 mph
