A train leaves station M and travels west at 35 km/hr. One hour later, a faster train leaves station M and also travels west of parallel track at 40 km/hr. How far from station M will the faster train catch the slower one?
--------------
1st train DATA:
rate = 35 km/hr ; time = x hrs. ; distance = 35x km
-----------------
2nd train DATA:
rate = 40 km/hr ; time = x-1 hrs ; distance = 40(x-1) km
-------------------
Equation:
distance = distance
35x = 40(x-1)
35x = 40x-40
-5x = -40
x = 8 hrs
------------------------
Distance for faster train: 8*40 = 320 km
