Answer 1

1). 448-192=256 (км) — проехал автомобиль. 2). 256:4=64 (км/ч) Ответ: 64 км/ч – скорость автомобиля.

Answer 2

Calculating the Speed of the Car

To calculate the speed of the car, we can use the formula:

Speed = Distance / Time

Given that the car needs to travel a total distance of 448 km and initially traveled for 4 hours before reaching a stop, we can calculate the speed of the car for the entire journey.

First, let's calculate the time it took for the car to travel the initial distance of 448 km - 192 km = 256 km.

The car traveled 256 km in 4 hours, so the speed for this part of the journey is:

Speed = Distance / Time = 256 km / 4 hours = 64 km/h Now, let's calculate the speed for the remaining distance of 192 km.

Speed = Distance / Time = 192 km / ? hours

To find the time it took to travel the remaining 192 km, we can use the formula:

Time = Distance / Speed

Given that the speed for the remaining distance is not provided, we can't calculate the exact speed for the entire journey with the information provided.

If you have the speed for the remaining distance, we can calculate the overall speed of the car for the entire journey.
