person goes to work on the 8th floor of a 10-story building. Unfortunately, there is a power outage and the elevator stops. It takes him 48 seconds to walk from the first floor to the 4th floor. How many seconds will it take to reach the 8th floor at the same speed? ?
某人到10层大楼的8层办事，不巧停电，电梯停开，他从一层走到4层楼梯需要48秒，请问以同样的速度往上走到8层，还需要多少秒才能到达？
