Question

Пешеход за 6 ч прошел 24 км. Какой путь проедет за это же время машина, двигаясь со скоростью в 15 раз больше, чем пешеход Как изменится решение задачи, если машина будет в пути вдвое больше пешехода?

Answer 1

Расчитываем скорость пешехода
24/6=4км/ч
высчитываем скорость автомобиля
4+15=19км/ч
получаем ответ номер 1
19*6=114км
получаем ответ 2
19*12=228км
видим что ответ возрастает в двое если это нужно в ответе

Answer 2

Problem Analysis

The pedestrian covers a distance of 24 km in 6 hours. We need to find out how far a car, traveling at a speed 15 times faster than the pedestrian, will travel in the same amount of time. Additionally, we need to determine how the solution to the problem changes if the car travels twice as long as the pedestrian.

Solution

To find the distance the car will travel in the same time, we can use the formula: distance = speed × time. Given that the car's speed is 15 times faster than the pedestrian's, and the time is the same, the distance covered by the car can be calculated as follows: ``` car_distance = car_speed × time car_distance = 15 × pedestrian_speed × time ``` Substituting the values: ``` car_distance = 15 × 24 km car_distance = 360 km ``` So, the car will travel 360 km in the same time.

If the car travels twice as long as the pedestrian, the time taken by the car would be 12 hours. Using the same formula, the distance covered by the car can be calculated as follows: ``` car_distance = car_speed × time car_distance = 15 × pedestrian_speed × 12 car_distance = 15 × 24 km × 12 car_distance = 360 km × 12 car_distance = 4320 km ``` So, if the car travels twice as long as the pedestrian, it will cover a distance of 4320 km.

Conclusion

In summary, the car will travel 360 km in the same time as the pedestrian, and if the car travels twice as long as the pedestrian, it will cover a distance of 4320 km.
