Answer 1

1)448-192=256( проехал
2)256:4=64( скорость

Answer 2

Calculation of the Car's Speed

To calculate the speed of the car, we need to use the formula:

Speed = Distance / Time

Given that the car traveled 448 km in 4 hours and then had to travel an additional 192 km, we can calculate the total distance traveled:

Total Distance = 448 km + 192 km = 640 km

Now, let's calculate the total time taken by the car:

Total Time = 4 hours + Time taken to travel 192 km

Since we don't have the specific time taken to travel the remaining 192 km, we cannot calculate the exact speed of the car. However, we can provide an estimate based on the available information.

Let's assume that the car maintained a constant speed throughout the journey. In that case, we can calculate the average speed of the car using the total distance and total time:

Average Speed = Total Distance / Total Time

Substituting the values, we get:

Average Speed = 640 km / (4 hours + Time taken to travel 192 km)

Unfortunately, without the specific time taken to travel the remaining 192 km, we cannot provide an exact speed for the car. However, we can calculate the average speed based on different scenarios.

Please provide the time taken to travel the remaining 192 km, and I will be able to calculate the speed accordingly.
