turner's treadmill runs with a velocity of -1.2m/s^2 and speed up at regular intervals during a half-hour workout. after 25 min, the treadmill has a velocity of -6.5m/s. what is the average acceleration of the treadmill during this period?

特纳的跑步机以 -1.2m/s的速度运行并以固定间隔加速在半小时中健身。25分钟后，跑步机的速度为-6.5m/s，求这段时间跑步机的平均加速度
题目不难但是有点怪，你的-1.2m/s^2是打错了吧
