Answer 1

480/8=60   скорость автобуса
60+36=96  скорость авто
480/96=5 ч авто  проедет 480км
480/4 =120скорость  на 480 км за 4 часа

Answer 3

Calculation of Time and Speed

To calculate the time it takes for a car to travel a distance of 480 km at a speed 36 km/h faster than the bus, we can use the formula:

Time = Distance / Speed

Let's calculate the time it takes for the car to travel the distance of 480 km at a speed 36 km/h faster than the bus:

1. Speed of the bus: 480 km / 8 hours = 60 km/h. 2. Speed of the car: 60 km/h + 36 km/h = 96 km/h. 3. Time taken by the car to travel 480 km: 480 km / 96 km/h = 5 hours.

Therefore, the car will take 5 hours to travel the same distance as the bus.

To calculate the speed at which the car needs to travel to cover the distance of 480 km in 4 hours, we can use the formula:

Speed = Distance / Time

Let's calculate the speed at which the car needs to travel to cover the distance of 480 km in 4 hours:

1. Time taken by the car: 4 hours. 2. Speed of the car: 480 km / 4 hours = 120 km/h.

Therefore, the car needs to travel at a speed of 120 km/h to cover the distance of 480 km in 4 hours.
