Let us assume as at when they meet, the time elapsed is x hours.
Fred 3 mi/h
John 2 mi/h
Distance = speed * time
Fred = 3x
John = 2x
Houses are 4miles apart.
So: 3x + 2x = 4 5x = 4
x = 4/5 hour = 0.8 hour or 0.8*60 = 48 minutes
Time elapsed is 0.8 hour or 48 minutes.

Step-by-step explanation:
The solution to the system is (1, 5)
The rule to represent the aritmathic sequence would be :
A(n) = 130 + (n-1) 13
the height in 13 days would be :
A(n) = 130 + (14-1) 13
A(n) = 130 + 169
= 299 inches
