------
Draw the picture.
Notice that distance for the 2 cars is the same when one overtakes the other.
---
1st Car DATA:
rate = 59 kmh ; time = x hrs ; distance = 59x km
-----
2nd Car DATA:
rate = 84 kmh ; time = x-1 hrs ; distance = 84(x-1) km
----
Equation:
distance = distance
59x = 84x - 84
25x = 84
x = 3.36 hrs
x-1 = 2.36 hrs
Distance of 2nd car: 2.36*84 = 198.24 km
