Hello!
Before Social Media , Many people liked the old classical way and they had there own way to communicate with people. With social media everything changed . Companies started to grow and real face to face communication was shrinking slowly . Kids locked themselves in there rooms to text friends and play games instead of playing outside. But technology does have a good affect for example if it wasn't for technology i wouldn't be able to help you right now ! If it wasn't for social media Wendy's wouldn't be able to Roast people . And contact over the phone would be limited .
HOPE I HELPED HAVE A BLESSED DAY!!
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
