let's say they catch-up to each other after t hour. 
so 
in t hour distance travelled by Renee 
d = speed × time = 50t
in t hour distance travelled by Kim 
d = speed × time = 60(t-1) + 0×1 = 60(t-1)
Note: here kim didn't covered any distance in first hour and in rest t-1 hour it travelled all distance 
now.as distance travelled by both is same so 
60(t-1) = 50t
60t -60 = 50t
adding 60 both sides
60t = 50t+60
subtracting 50t both sides
60t -50t = 50t+60 - 50t
10t = 60
dividing by 10 both sides
t = 60/10 = 6
so in 6 hour both will catch-up to each other
