Question

Из двух городов одновременно навстречу друг другу выехали автобус и легковая машина. В пути они вс трети лись и отьехали друг от друга на расстоянии 191/2 км.За это время автобус проехал 83 1/5км,а легковая -120 3/4 км. Найдите расстояние между городами.

Answer 1

1) 120 3/4+83 1/5=203 15/20+4/20= 203 19/20(км) путь, проделанный за это время двумя машинами.
2) 203 19/20-19 1/2=184 19/20-10/20=184 9/20(км) расстояние между городами.
Ответ: 184 9/20км расстояние между городами.

Answer 2

Из двух городов одновременно навстречу друг другу выехали автобус и легковая машина. В пути они встретились и отъехали друг от друга на расстоянии 19 1/2 км. За это время автобус проехал 83 1/5 км, а легковая машина - 120 3/4 км. Найдите расстояние между городами.

Solution:

Let's assume the distance between the two cities is x km.

According to the given information, the bus traveled 83 1/5 km and the car traveled 120 3/4 km. Together, they covered 19 1/2 km.

We can set up the following equation to solve for x:

x = (83 1/5) + (120 3/4) + 19 1/2

To simplify the equation, we need to convert all the mixed numbers to improper fractions:

x = (83 1/5) + (120 3/4) + 19 1/2 x = (83 + 1/5) + (120 + 3/4) + 19 1/2 x = (83/1 + 1/5) + (120/1 + 3/4) + 19 1/2 x = (83/1 + 1/5) + (120/1 + 3/4) + (19 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/4) + (19/1 + 1/2) x = (83/1 + 1/5) + (120/1 + 3/
