Question

Автобус и машина одновременно выехали из одного населённого пункта в противоположный направлениях. Скорость автобуса 53 км/ч,а скорость машина -73 км/ч. Какое расстояние будет между ними через 4 часа?

Answer 1

1) 53+73=126 (км/ч) - вместе.
2)126•4=504(км) - S между ними через 4 часа
Ответ: 504 км будет между ними через 4 часа.

Answer 2

53+73=126
126умножить4 =504

Answer 3

Calculation of Distance between the Bus and Car

To calculate the distance between the bus and the car after 4 hours, we need to determine the distance each vehicle has traveled in that time.

Given: - Speed of the bus = 53 km/h - Speed of the car = -73 km/h (assuming the negative sign indicates the opposite direction)

To find the distance traveled by each vehicle, we can use the formula:

Distance = Speed × Time

For the bus: Distance traveled by the bus = 53 km/h × 4 hours = 212 km

For the car: Distance traveled by the car = -73 km/h × 4 hours = -292 km

Since the car is traveling in the opposite direction, we consider the distance as negative.

Calculation of the Distance between the Bus and Car

To find the distance between the bus and the car after 4 hours, we need to add the absolute values of their distances and take the absolute value of the sum:

Distance between the bus and car = |Distance of the bus| + |Distance of the car|

Distance between the bus and car = |212 km| + |-292 km| = 212 km + 292 km = 504 km

Therefore, the distance between the bus and the car after 4 hours will be 504 km.

Please note that the negative sign in the speed of the car indicates the opposite direction, but when calculating the distance, we consider the absolute values.
