Barron's 閱讀 - 英檢

不好意思 英文很差

想請問一下 barron's model test1 裡面的閱讀第二篇

第20題
"The loss of heat to water occurs 50 to 100 times more rapidly than heat loss
to air."


50 to 100 times 是指幾倍? 能否請板上大大分析這個句子
答案是2倍"because heat is loss in water twice as fast as it is in air"

另外想問
"The evolution of stars between 50 and 100 times the mass of the Sun"
中文是50 ~100倍之間嗎？？　被前面的句子搞混了
