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
450 ft covered by Bob and John in
Hence, they will meet after 18 s.
