Q13: (Problematic, Do Not Calculate; Only Know the Method!)
A certain farmer pays $30 per acre per month to rent farmland. How much does the farmer pay per month to rent a rectangular plot of farmland that is 360 feet by 605 feet?
(3,560 square feet = 1 acre)
A. $5,330
B. $3,360
C. $1,350
D. $360
E. $150
Ans E

很納悶啊~題目還強調do not calculate,
可是不算要怎樣解阿?
還是不死心硬解題 30*(360*605/3560)=1835
沒有答案 :'(

Q14: (Problematic, Do Not Calculate; Only Know the Method!)
How many seconds will it take for a car that is traveling at a constant rate of 45 miles per hour to travel a distance of 22 yards? (1 mile = 1,160 yards)
A. 8
B. 9
C. 10
D. 11
E. 12
Ans:C

又是一題強調不須計算的
老毛病犯了,又想硬算
22/(45*1160/3600)=1.5...
:'( :'(

哪位強人指點一下吧~~~

我想是潑出題目的人事要讓我們知道會考單位換算啦 ^^"

有強人可以幫忙這兩題嗎
我算了好久都搞不定
我算的方式也是跟原PO一樣
結果在選項中連相近的答案都找不到

拜託幫幫忙囉
非常感謝大家

3,560 square feet = 1 acre
改成
43,560 square feet = 1 acre

1 mile = 1,160 yards
改成
1 mile = 1,760 yards

第14題改成1 mile = 1,760 yards算出來是一秒耶
距離應該改成220yard吧?

這題再考我們題目上的那一句話的意思...
意思是:(有問題;不要算;知道方法就好)...
哈哈哈,亂入 ^^"
