the ratio of distance from home to work time to drive from home to work was the same for Bill and Sue that day这句话意思是说bill和sue的速度相同。但是省略drive from home to work来看，变为the ratio of distance time to was the same~~好奇怪，求分析？？
(distance from home to work FOR BILL / time to drive from home to work FOR BILL) = (distance from home to work FOR SUE / time to drive from home to work FOR SUE)
我觉得原句应该有问题 the ratio of distance from home to work TO time to drive from home to work was the same for Bill and Sue that day
