Short Answer

Expert verified

Elena enters a hall, sees a seat 40 m directly ahead, and begins walking toward it at a constant pace, covering the first 10 m in 10 seconds. But then Elena notices that Susan is heading toward the same seat, so Elena walks more quickly to cover the remaining 30 m in another 10 seconds, beating Susan to the seat. Elena stands next to the seat for 10 seconds to remove her backpack.
