Question

До турбазы автобус шёл 2 ч со скоростью 68км.ч. Затем водитель увеличил скорость на 15 км.ч и ещё через 2 ч автобус приехал на конечную станцию. Сколько километров проехал автобус за это время?

Answer 1

1) 68*2= 136 (км)-до турбазы 2) 68+15= 83 (км/ч)- увеличенная скорость 3) 83*2= 166 (км)- после 4) 136+166= 302(км) Ответ: Автобус проехал 302 километра

Answer 2

1)68*2=136(км)-сначала проехал 2)68+15=83(км/ч)-скорость 3)83*2=166(км)-потом проехал 4)136+166=302(км)-всего

Answer 3

Calculation of the Distance Traveled by the Bus

To calculate the distance traveled by the bus, we need to consider the different stages of its journey.

1. First Stage: The bus traveled for 2 hours at a speed of 68 km/h.

To calculate the distance traveled during this stage, we can use the formula: Distance = Speed × Time.

Therefore, the distance traveled during the first stage is: Distance = 68 km/h × 2 h = 136 km.

2. Second Stage: After 2 hours, the driver increased the speed by 15 km/h.

To calculate the distance traveled during this stage, we need to know the duration of the second stage. However, the given information does not specify the duration of the second stage.

Without the duration of the second stage, we cannot accurately calculate the distance traveled during this stage.

3. Final Stage: After the second stage, the bus arrived at the final station.

Unfortunately, the given information does not provide any details about the distance or time taken during the final stage.

Therefore, based on the given information, we can only calculate the distance traveled during the first stage, which is 136 km. The distances traveled during the second stage and the final stage cannot be determined without additional information.

Please provide more details about the duration of the second stage and any other relevant information so that we can calculate the total distance traveled by the bus.
