我来翻译下,
1.如果每个需要8美分,那么求两个巧克力芯片和3个花生酱饼干的费用
应该是40美分吧
2.如果Ms.McCarthy开车出游先每小时30英里,开了3 / 4小时,后每小时55英里,开了1.5小时,请问Ms.McCarthy开了多少英里?
3/4×30+55×1.5=105英里

成本两个巧克力芯片和3个花生酱饼干的cookie费用如果每个8美分
数英里来到了Ms.McCarthy如果她开车30英里每小时3 / 4小时55英里每小时1.5小时。

第二题
麦克卡什小姐出外旅行，她前3/4小时驾车的速度是每小时30英里，后1.5小时驾车的速度是55英里，她共行驶了
3/4×30+55×1.5=105英里
第一题,看不明白.好象已知条件不够
