Question

два автобуса двигались с одинаковой скоростью.Первый автобус был в пути 7ч,второй 3ч.С какой скоростью двигался автобус если первый из них проехал на 240 км больше чем второй

Answer 1

     1) Способ

х - скорость автобуса

7х-3х=240

4х=240

х=240/4

х=60 км/ч - скорость автобуса

    2) Способ

7-3=4(ч)

240:4=60(км/ч)

Ответ: 60 км/ч

Answer 2

Calculating the Speed of the Bus

To calculate the speed of the bus, we can use the formula:

speed = distance / time

Given that the first bus traveled 240 km more than the second bus, and the time taken by the first bus was 7 hours and the second bus was 3 hours, we can calculate the speed of each bus.

Let's denote: - Speed of the first bus as S - Speed of the second bus as S'

The distance traveled by the first bus is 240 km + distance traveled by the second bus.

Using the formula, we can set up the following equations:

1. For the first bus: 240 + S * 7 2. For the second bus: S' * 3

Now, we can solve for the speed of the buses.

Calculating the Speed of the First Bus

Using the given information, we can calculate the speed of the first bus:

240 + S * 7 = S' * 3

Solving for S: 240 + 7S = 3S'

Calculating the Speed of the Second Bus

We can also calculate the speed of the second bus:

S' = 240 + 7S / 3

Now, we can use these equations to calculate the speeds of the buses.
