Question

группа туристов (220 человек) полностью заполнила несколько 50-местных и 35-местных автобусов.Известно,что всего было подано 5 автобусов.Сколько 50-местных и сколько 35-местных автобусов было занято туристами?решите пожалуйста задачу

Answer 1

Только логически 50+35=85чел в двух разных автобусах 220-85=135=2 по 50 и 1 по 35 чел .ответ 3 по 50 чел и 2 по 35 чел

Answer 2

Problem Analysis

We are given that a group of tourists, consisting of 220 people, completely filled several 50-seat and 35-seat buses. We also know that a total of 5 buses were used. We need to determine how many 50-seat buses and how many 35-seat buses were occupied by the tourists.

Solution

Let's assume that x represents the number of 50-seat buses and y represents the number of 35-seat buses. We can set up a system of equations to solve for x and y.

1. The total number of people on the 50-seat buses is 50x. 2. The total number of people on the 35-seat buses is 35y. 3. The total number of people in the group is 220.

Using these equations, we can write the following system of equations:

Equation 1: 50x + 35y = 220 Equation 2: x + y = 5

We can solve this system of equations to find the values of x and y.

Solution Steps

1. Solve Equation 2 for x: x = 5 - y. 2. Substitute the value of x in Equation 1: 50(5 - y) + 35y = 220. 3. Simplify the equation: 250 - 50y + 35y = 220. 4. Combine like terms: -15y = -30. 5. Divide both sides by -15: y = 2. 6. Substitute the value of y in Equation 2 to find x: x + 2 = 5. 7. Solve for x: x = 3.

Therefore, there were 3 50-seat buses and 2 35-seat buses occupied by the tourists.

Answer

The group of tourists, consisting of 220 people, occupied 3 50-seat buses and 2 35-seat buses
