Answer 2

Calculation of the Total Distance Traveled by the Car

To calculate the total distance traveled by the car, we need to add up the distances covered during each time interval.

The car traveled for 3 hours at a speed of 48.4 km/h, and then for 5 hours at a speed of 56.6 km/h.

Let's calculate the distances covered during each time interval:

- Distance covered in the first 3 hours: 3 hours × 48.4 km/h = 145.2 km- Distance covered in the next 5 hours: 5 hours × 56.6 km/h = 283 km Now, let's calculate the total distance traveled by adding up the distances covered during each time interval:

- Total distance traveled = Distance covered in the first 3 hours + Distance covered in the next 5 hours - Total distance traveled = 145.2 km + 283 km - Total distance traveled = 428.2 km

Therefore, the car traveled a total distance of 428.2 km during the given time period.
