Answer 1

Ответ:

Пошаговое объяснение:

Время автобуса в пути:

240/60=4 часа.

Расстояние, которое проехала машина:

82·3=246 км.

Скорость самолета:

600/2=300 км/ч.

Answer 2

Problem 1: Autobus

To solve the problem for the autobus, we need to find the time it takes to travel a distance of 240 km at a speed of 60 km/h.

Let's use the formula: distance = speed × time.

Given: - Speed of the autobus: 60 km/h - Distance traveled by the autobus: 240 km

We need to find the time taken by the autobus.

Let's substitute the given values into the formula and solve for time:

240 km = 60 km/h × time

To find the value of time, we can divide both sides of the equation by 60 km/h:

time = 240 km / 60 km/h

Calculating this, we get:

time = 4 hours

Therefore, it takes the autobus 4 hours to travel a distance of 240 km at a speed of 60 km/h.

Problem 2: Car

To solve the problem for the car, we need to find the distance traveled by the car when it travels at a speed of 82 km/h for 3 hours.

Let's use the formula: distance = speed × time.

Given: - Speed of the car: 82 km/h - Time taken by the car: 3 hours

We need to find the distance traveled by the car.

Let's substitute the given values into the formula and solve for distance:

distance = 82 km/h × 3 hours

Calculating this, we get:

distance = 246 km

Therefore, the car travels a distance of 246 km when it travels at a speed of 82 km/h for 3 hours.

Problem 3: Airplane

To solve the problem for the airplane, we need to find the speed of the airplane when it travels a distance of 600 km in 2 hours.

Let's use the formula: distance = speed × time.

Given: - Distance traveled by the airplane: 600 km - Time taken by the airplane: 2 hours

We need to find the speed of the airplane.

Let's substitute the given values into the formula and solve for speed:

600 km = speed × 2 hours

To find the value of speed, we can divide both sides of the equation by 2 hours:

speed = 600 km / 2 hours

Calculating this, we get:

speed = 300 km/h

Therefore, the airplane travels at a speed of 300 km/h when it travels a distance of 600 km in 2 hours.
