    state the distances in km of A and B from O after t hours

    因為是 "distanceS" 所以是複數

    所以要的是兩個: O-A 的距離 與 O-B 的距離

    希望我沒有誤會題意

    題目應該是說: A船由原點O出發向東邊走, 時速10km; B船在原點O的南方100公里處, 朝北以每小時20km的速度朝O前進

    問: t小時後, O點到AB線段的距離?

    我想這題你可能要分成 3 種狀況去計算

    一種是 t < 5

    一種是 t = 5

    一種是 t > 5

    句中的t hour沒有給明確的小時數嗎?
