San Diego and Bakersfield are 232 miles apart. A truck driver drives from San Diego to Bakersfield and back, which takes a total of 8 hours. What is his rate in miles per hour?

Question

A.
29 miles per hour
B.
58 miles per hour
C.
116 miles per hour
D.
232 miles per hour

Answer 1

To find the rate of the truck driver in miles per hour, we first need to determine the total distance he traveled for the round trip and then divide that by the total time taken.

1. Calculate the distance for the round trip:

   • The distance from San Diego to Bakersfield is 232 miles.
   • The round trip distance is: \[ \text{Total Distance} = 232 \text{ miles (to Bakersfield)} + 232 \text{ miles (back to San Diego)} = 464 \text{ miles} \]

2. Total time taken:

   • The total time for the trip is 8 hours.

3. Calculate the rate (speed):

   • The rate is calculated by dividing the total distance by the total time: \[ \text{Rate} = \frac{\text{Total Distance}}{\text{Total Time}} = \frac{464 \text{ miles}}{8 \text{ hours}} = 58 \text{ miles per hour} \]

Therefore, the truck driver's rate is 58 miles per hour, which corresponds to option B.
