Answer:

18 s

Step-by-step explanation:

We are given that

Distance between Bob and John=450 feet

Speed of Bob=11ft/s

Speed of John=14 ft/s

We have to find the time after they will meet when they are travel towards to each other.

Total distance traveled by Bob and John in 1 s=11+14=25 ft

25ft covered by Bob and John in 1 s

1 ft covered by Bob and John in [tex]\frac{1}{25}s[/tex]

450 ft covered by Bob and John  in [tex]\frac{1}{25}\times 450=18 s[/tex]

Hence, they will meet after 18 s.

Answer:

18 seconds

Step-by-step explanation:

450 divided by 11+14=18
