Question

Грузовой автомобиль движется со скоростью 60 км/ч. Впереди него на расстоянии 30 км едет автобус со скоростью80км/ч. какое расстояние будет между ними через 3 часа

Answer 1

80-60=20 скорость удаления
20 умножить на 3=60 км расстояние которое будет через 3 часа

Answer 2

(80-60)•3+30=90(км)
Ответ: 90 километров

Answer 3

Calculation of the Distance between the Truck and the Bus

To calculate the distance between the truck and the bus after 3 hours, we need to consider their speeds and the time they have been traveling.

Given: - The truck is moving at a speed of 60 km/h. - The bus is moving at a speed of 80 km/h. - The bus is 30 km ahead of the truck.

To find the distance between them after 3 hours, we can use the formula: distance = speed × time.

Let's calculate the distance traveled by the truck and the bus separately after 3 hours.

For the truck: - Speed = 60 km/h - Time = 3 hours

Using the formula, we can calculate the distance traveled by the truck after 3 hours: distance_truck = speed_truck × time = 60 km/h × 3 hours = 180 km.

For the bus: - Speed = 80 km/h - Time = 3 hours

Using the formula, we can calculate the distance traveled by the bus after 3 hours: distance_bus = speed_bus × time = 80 km/h × 3 hours = 240 km.

Now, let's find the distance between them after 3 hours. Since the bus is ahead of the truck, we subtract the distance traveled by the truck from the distance traveled by the bus: distance_between = distance_bus - distance_truck = 240 km - 180 km = 60 km.

Therefore, the distance between the truck and the bus after 3 hours will be 60 km.
