B 455455
C 385385
D 495495
To calculate the distance traveled, we need to multiply the average speed by the time traveled for each segment.
For the first segment:
Distance = Speed * Time = 70 miles/hour * 2.5 hours = 175 miles
For the second segment:
Distance = Speed * Time = 80 miles/hour * 3.5 hours = 280 miles
The total distance traveled is the sum of the distances for each segment:
Total distance = 175 miles + 280 miles = 455 miles
Therefore, the correct answer is B) 455455.
