2 「16km離れた目的地に地下鉄と徒歩で行くと、目的地まで48分かかりました。 地 下鉄には何分乗っていたのでしょうか。 地下鉄の平均時速は時速35km 徒歩の平均 時速は時速5kmとします。」 という問題をSさんとDさんとHさんが一緒に考えていたときの会話が以下の文章で ある。三人の会話を読み、次の問いに答えなさい。 分速 km 分速/2km Sさん 「これは地下鉄に乗っていた時間を分、徒歩にかかった時間を1分と置くと. 方程式が立てられるよ。」 Dさん Hさん 「地下鉄に乗っていたx分と置くなら、徒歩にかかった時間を分と置かずに, 方程式を立てて 13 でいいのでは?」 Sさん 「それでもいいけど, 連立方程式を作りたい。 地下鉄に乗っていた時間をx時 間,徒歩にかかった時間をy時間と置いて,方程式を立ててx+y=414で もいいか。」 12 になるね。」 「そうすると式はx+y=48と 35x+5y=16 Dさん 「そもそも文字で置かずにできないかな。 48分を全て徒歩で移動したとする と, 15km移動したことになり、目的地まで足りない距離を時速 1617kmで 割り, 出てきた数値の時間の単位を変換すると答えがでるよ。」 Hさん 「他の考え方をすると, 16km離れた目的地まで48分かかっているので,平均 時速は時速20kmと計算できる。 これより 徒歩と地下鉄の時間の比は18:19 となるので答えを求めることもできるよ。」 (1) 12 13 14 に当てはまる式として最も適当なものを,それぞれ1~9 から選び なさい。 12.② 13-6 1 35x+5y=48 3 2100x+300y=16 5 35x+5y=16 2 SEASES NO 7 35x+5(48-x)=16 (2) 15 7 11/2x+ /1/12 (1/2-x) = 16 9 7 1 -x+. y=16 12 12 7 ④ 1/2x+1/22-48 4 y=48 ES-03 HA 7. ⑥112x+ /1/12 (48-x)=16 6 355(-x)=16 19 に当てはまる数値を求めなさい。 18.① 19.1 -2-
