Answer:
The truck driver's rate is 58 miles per hour.
Explanation:
The distance between San Diego and Bakersfield is 232 miles. Since the driver travels from San Diego to Bakersfield and back, the total distance covered is 2 times 232 miles, which equals 464 miles.
The total time taken for the round trip is given as 8 hours.
To find the average speed in miles per hour, we divide the total distance by the total time:
464 miles / 8 hours = 58 miles per hour
