1. \(\frac{7}{19}\times\frac{8}{11}+\frac{7}{19}\times\frac{3}{11}+\frac{12}{19}\)

\(=\frac{7}{19}\left(\frac{8}{11}+\frac{3}{11}\right)+\frac{12}{19}\)

\(=\frac{7}{19}\times1+\frac{12}{19}=\frac{19}{19}=1\)

2. \(\frac{\frac{2}{5}+\frac{2}{7}-\frac{2}{9}-\frac{2}{11}}{\frac{4}{5}+\frac{4}{7}-\frac{4}{9}-\frac{4}{11}}\)

\(=\frac{\frac{2}{5}+\frac{2}{7}-\frac{2}{9}-\frac{2}{11}}{2\left(\frac{2}{5}+\frac{2}{7}-\frac{2}{9}-\frac{2}{11}\right)}=\frac{1}{2}\)

40 phút = \(\frac{2}{3}h\)

Gọi vận tốc ô tô thứ nhất, thứ hai, thứ ba đi từ A đến B lần lượt là v₁, v₂, v₃ ; thời gian tương ứng của ba ô tô là t₁, t₂, t_3^.

Do vận tốc (km/h) và thời gian di chuyển (h) là hai đại lượng ti lệ nghịch nên ta có:

v₁ . t₁ = v₂ . t₂ = v₃ . t₃ mà v₃ - v₁ = 3 ; t₁= \(\frac{2}{3}\); t₃= \(\frac{5}{8}\)nên: \(\frac{v_1}{\frac{1}{t_1}}=\frac{v_2}{\frac{1}{t_2}}=\frac{v_3}{\frac{1}{t_3}}=\Rightarrow\frac{v_1}{\frac{1}{\frac{2}{3}}}=\frac{v_2}{\frac{1}{\frac{5}{9}}}=\frac{v_3}{\frac{1}{\frac{5}{8}}}\)

Áp dụng tính chất của dãy tỉ số bằng nhau, ta có:

\(\frac{v_1}{\frac{1}{\frac{2}{3}}}=\frac{v_2}{\frac{1}{\frac{5}{9}}}=\frac{v_3}{\frac{1}{\frac{5}{8}}}=\frac{v_3-v_1}{\frac{1}{\frac{5}{8}}-\frac{1}{\frac{2}{3}}}=\frac{3}{\frac{1}{10}}=30\)
