Question

Из двух городов одновременно навстречу друг другу выехали 2 автобуса. Скорость первого автобуса 25 км/ч, скорость второго 50 км/ч. Первый автобус прошёл до встречи 100 км. Сколько километров прошёл до встречи второй автобус?

Answer 1

100:25=4(часа)-прошел первый автобус до встречи
50*4=200(км)-прошел второй автобус до встречи

Answer 3

Problem Analysis

Two buses are traveling towards each other from two different cities. The speed of the first bus is 25 km/h, and the speed of the second bus is 50 km/h. The first bus has traveled 100 km before they meet. We need to find out how many kilometers the second bus has traveled before the meeting.

Solution

To find out how many kilometers the second bus has traveled before the meeting, we can use the formula:

Distance = Speed x Time

Let's assume the time taken by the second bus to reach the meeting point is 't' hours.

The distance traveled by the first bus is given as 100 km, and its speed is 25 km/h. Therefore, the time taken by the first bus is:

Time taken by the first bus = Distance / Speed = 100 km / 25 km/h = 4 hours

Since both buses are traveling towards each other, the total time taken for the second bus to reach the meeting point is the sum of the time taken by both buses:

Total time taken = Time taken by the first bus + Time taken by the second bus = 4 hours + t hours = (4 + t) hours

Now, we can calculate the distance traveled by the second bus using the formula:

Distance = Speed x Time

Substituting the values, we have:

Distance traveled by the second bus = Speed of the second bus x Time taken by the second bus = 50 km/h x t hours = 50t km

Therefore, the second bus has traveled 50t km before the meeting.

Calculation

To find the value of 't', we need more information or assumptions about the meeting point or the time taken by the second bus. Without that information, we cannot determine the exact distance traveled by the second bus before the meeting.

If you have any additional information or assumptions, please provide them so that we can calculate the distance traveled by the second bus accurately.
