Question

АВТОМОБИЛЬ ЗА 4Ч. ПРОЕХАЛ 312 КМ. КАКОЕ РАССТОЯНИЕ ПРОЕДЕТ АВТОМОБИЛЬ ЗА ЭТО ЖЕ ВРЕМЯ, ЕСЛИ УМЕНЬШИТ СКОРОСТЬ НА 5КМ/Ч?

Answer 1

312:4=78(км\ч)-скорость за первый путь
78-5=73(км\ч)-скорость
73 умножить 4=292(км)-расстояние
ответ:292км

Answer 2

1 способ.
1) 312/4=78 (км/ч)
2) (78-5)*4=73*4=292 (км)
2 способ.
1) 312-4*5=292 (км)

Answer 3

Calculation of Distance Traveled

To calculate the distance traveled by a car in 4 hours at a reduced speed, we need to know the initial speed of the car. Unfortunately, the provided question does not mention the initial speed of the car. However, we can still provide a general formula to calculate the distance traveled based on the initial speed and the time taken.

The formula to calculate distance is:

Distance = Speed x Time

Let's assume the initial speed of the car is x km/h. The time taken is 4 hours. We need to find the distance traveled when the speed is reduced by 5 km/h.

Using the formula, we can calculate the distance traveled at the initial speed:

Distance1 = x km/h x 4 hours

To find the distance traveled at a reduced speed, we need to subtract 5 km/h from the initial speed:

Reduced Speed = x km/h - 5 km/h

Now, we can calculate the distance traveled at the reduced speed:

Distance2 = (x km/h - 5 km/h) x 4 hours

Please note that without the initial speed, we cannot provide a specific numerical answer. However, the above formulas can be used to calculate the distance traveled based on the given information.
