為什麼這兩張圖是一樣的?還有這題要怎麼判斷?

(33.~35.) People in Taiwan never worry about getting hungry at night when there is nothing at home. They can walk to the convenience stores and get anything they I want. In fact, in Taiwan, it is not possible that people fail to find a convenience store because it is part of our life. Convenience stores are working 24/7. In other words, finding a place to sit down and take a rest anytime is a piece of cake. In order to grow business, shopkeepers use some smart ways to have the buyers spend more. First, they put the most popular items at the buyers'eye level to let them see the items easily and often. Second, they drive the buyers to buy something cheap and small without thinking too much or give shoppers a special offer like "Buy One And Get One Free.” Third, they try to have the buyers stay at the convenience stores as long as possible by setting up a seating area. They think the buyers will buy one drink after another once they stay longer. In a study, 73 teenagers answer two of the questions. The pictures below show their interesting answers. Which of the following do you like? The taste of the foods.

綜合觀念 道路 「反應時間」是指駕駛人從發現狀況到踩下煞車所需的時間,「煞車時間」則是指 駕駛人踩煞車直到汽車靜止的時間,這兩段時間內汽車繼續前進的距離分別為「反應距 「離」與「煞車距離」,反應距離與煞車距離之和稱為「停車距離」,此距離關係到車輛可 否安全停下來或發生碰撞。 地面摩擦係數愈大,則車輛行駛時所受的摩擦力愈大,以臺灣多數的柏油路面摩擦 係數約為0.75 計算,交通部曾頒布「煞車距離與行車速度對照表」,如下表。 車速(公里/時) 10 20 30 40 50 60 70 80 反應距離(公尺) 2.08 4.16 6.25 8.33 10.41 12.5 14.58 16.66 煞車距離(公尺) 0.52 2.09 4.71 8.38 13.09 18.86 25.68 33.55 D 128. 明翊在市區駕駛汽車,他以70km/hr 等速直線行駛時,看見正前方路障,經ㄊ秒 的反應時間後踩煞車,再經tz秒汽車完全靜止。假設從踩煞車至完全靜止,汽車 = 19.44m/s) 所受合力大小為一定值,下列何者最符合此敘述?(70km/hr (A)v(m/s) 19.44 14.581 25.68 →t(s) (B) v(m/s) 19.44 14.581 25.68 -t(s) 0 t₁ v(m/s) 19.44 0 14.58 25.68 t₁ →t(s) (D) 0 v(m/s) 19.44 14.581 25.68 0 t₁ →t(s) 29.如果阿宜駕駛汽車經過摩擦係數為0.6的路面,則表中煞車距離與行車速度對照 & 表的反應距離與煞車距離,應如何調整? A (A)反應距離與煞車距離數值應變大 (B)反應距離與煞車距離數值應不變 (C)反應距離不變,煞車距離則變大 (D)反應距離變大,煞車距離則不變
