D Correct answer
Explanation

Distance 1 = 76 * 3 = 228 miles. Distance 2 = 178 miles. Total distance = 228 + 178 = 406 miles. Total time = 3 + 4 = 7 hours. Average speed = 406 / 7 = 58 mph.

AI explanation

The car travels 76 miles per hour for 3 hours, covering 228 miles, and then travels another 178 miles in 4 hours. The total distance is 406 miles and the total time is 7 hours. Using the average speed formula, 406 divided by 7 gives an average speed of 58 miles per hour.
