60 Km/hr and 40 Km/hr

Explanation:
Let the speed of two cars be S1 & S2
From given condition that, If they travels towards each other,they meet in 1 hour
S1+S2 = 100 Km/hr ->1
From other condition, If cars travels in same direction at different speed,they meet in 5 hours
S2*5 = (S1*5)-100 -> 2 (as Car1 need to travel 100 Km more than Car2 in 5 hours)

From 1, S2 = 100-S1
Substituting in 2, (100-S1)*5 = (S1*5)-100
=> 500 - 5S1 = 5S1 -100
=> 600 = 10S1
=> S1 = 60 Km/hr
Hence S2 = 100-60 = 40 Km/hr
