Step-by-step explanation:
★Given -
Roger
- Initial position = 32nd floor
- Speed = 34 floors/min
Edward
- Initial position = 98th floors
- Speed = 98 floors/min
★To find -
- The floor on which Roger and Edward will meet.
★Solution -
Let their paths cross after 't' minutes.
Distance covered by Roger in t minutes = 34t
Distance covered by Edward in t minutes = 98t
Hence, number of floors covered by Roger in 1/2 mins = 34 × 1/2 = 17.
∴ their paths cross at (32 + 17)th i.e. 49th floor.
