¢¹ The speed of the car that departed first: V1 (km/hr) 
¢¹ The speed of the car that departed later: V2 (km/hr), (V1 < V2)
¢¹ Departing time interval: dt (hr) 
Let T (hr) be the time it took for the car that departed later to meet the car that departed first, then, 

V2 * T = V1 * dt + V1 * T 

Thus, 

(V2 - V1) * T = V1 * dt 



Thus, the distance to meet from the departing point, L (km), is :
