對不起~我不知道要貼題目XD
如下
請各位大大幫忙囉
Stations X and Y are connected by two separate, straight, parallel rail lines that are 250 miles long. Train P and train Q simultaneously left Station X and Station Y, respectively, and each train traveled to the other’s point of departure. The two trains passed each other after traveling for 2 hours. When the two trains passed, which train was nearer to its destination?
(1)At the time when the two trains passed, train P had averaged a speed of 70 miles per hour.
(2)Train Q averaged a speed of 55 miles per hour for the entire trip.
這題答案是(C)
我想問的是為何不是(D)?
問哪一輛比較接近目的地的話
不是算誰走的比較遠就比較接近的意思嗎??
那麼~~兩個條件單獨的狀況下都可以判斷出啊???
