: 在第237&238頁的地方，謝謝。
: 12.A truck departed from Newton at 11:53 a.m and arrived in Far City,
: 240 miles away, at 4:41 p.m. on the same day. What was the approximate
: average speed of the trunck on this trip?
: (A)16/1200 MPH
: (B)240/288 MPH
: (C)1494/240 MPH
: (D)50 MPH
: (E)5640/5 MPH
: 答案是 D
總費時4:48跑了240miles
240 / (24/5) = 50
: 16.Which of the following fractions expressed in the form p/q is most nearly
: approximated by the decimal .PQ, where P is tenths' digit and Q is the
: hundredth' digit?
: (A)1/8
: (B)2/9
: (C)3/4
: (D)4/5
: (E)8/9
: 答案是 E
哪一個p/q最接近0.pq?
1/8 = 0.125
2/9 = 0.22222
3/4 = 0.75
4/5 = 0.8
8/9 = 0.88888
: 23.The diagonal of the floor of a rectangular closet is 15/2 feet. The

: square feet?
: (A)37
: (B)27
: (C)54/4
: (D)21/4

: 答案是 B
長方形對角線為15/2
短邊9/2
所以長邊為6
9/2 X 6 = 27
