: : 想請問各位神人,
: : GWD3-14
: : 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
: : 但是小的怎麼解都解不到10秒的答案,是否題目有所誤讀?
: : 感謝各位神人不嫌棄的回答
: 請改成 (1 mile = 1,760 yards)
: 220/(22x1,760) HR = 220/(22x1,760) x 3,600 (Secs) = 10 (Secs)
請問D大,如果是用1760來解,我的解法會變成:
45*1760/60*60=22 yard/per sec,
22 yard/22=1?
請問是那個地方解題順序還是哪裡出錯了呢?
感激不盡~
