Answer:
(E) None of these
Step-by-step explanation:
Let's calculate the difference in their rates:
\(63 - 57 = 6\) floors per minute.
Now, find the difference in the floors they start on:
\(51 - 11 = 40\) floors.
Divide the difference in starting floors by the difference in rates:
\(40 / 6 = 6\) minutes.
Now, Steve and Stephen will meet \(6\) minutes after they start.
In those \(6\) minutes, Steve's elevator will have gone up \(57 \times 6 = 342\) floors.
So, \(11 + 342 = 353\) is the floor where they will cross each other.
Therefore, the correct option is E) None of these
Answer is 31st floor they will meet (calculate the velocity)
