Question

Один автобус находился в пути 12ч, а второй – 5ч. Первый автобус проехал на 490 км больше, чем второй. Сколько километров проехал каждый автобус, если они двигались с одинаковой скоростью?​

Answer 1

Решение:

1) 12-5=7(часов) - первый автобус ехал дольше чем другой.

2) 490:7=70(км/час) - скорость автобусов.

3) 70х5=350 (км) - проехал второй автобус.

4) 70х12=840 (км) - проехал первый автобус.

Ответ: 1 автобус 350 км, 2 автобус 840 км.

Answer 2

Ответ:

Пошаговое объяснение:

1) 12 - 5 = 7 (часов) - разница между 1 и 2 автобусом

2) 490 : 7 = 70 (км/ч) - скорость 1 и 2 автобуса

3) 12 * 70 = 840 (км) - проехал 1 автобус

4) 5 * 70 = 350 (км) - проехал 2 автобус

5) 850 - 350 = 490 (км) проехал больше 1 автобус

Ответ: 840км; 350км

Answer 3

Problem Analysis

We are given two buses that have traveled for different durations. The first bus traveled for 12 hours, while the second bus traveled for 5 hours. The first bus traveled 490 km more than the second bus. We need to determine the distance traveled by each bus, assuming they were traveling at the same speed.

Solution

Let's assume the speed of both buses is x km/h.

The distance traveled by the first bus can be calculated using the formula: Distance = Speed × Time

For the first bus, the distance is given as 490 km more than the distance traveled by the second bus. So we can write the equation as: Distance of first bus = Distance of second bus + 490

Substituting the formula for distance, we get: Speed × Time of first bus = Speed × Time of second bus + 490

Since both buses traveled at the same speed, we can cancel out the speed from both sides of the equation: Time of first bus = Time of second bus + 490

We are given that the time of the first bus is 12 hours and the time of the second bus is 5 hours. Substituting these values into the equation, we get: 12 = 5 + 490

Simplifying the equation, we find: 7 = 490

This equation is not possible, as 7 cannot be equal to 490. Therefore, there is no solution to this problem.

Conclusion

There is no solution to this problem because the given information leads to an equation that is not possible.
