B Correct answer
Explanation

Distance = speed * time. Time taken at 50 mph from 11:30 am to 4:00 pm is 4.5 hours. Distance = 50 * 4.5 = 225 miles. At 75 mph, time = 225 / 75 = 3 hours. 11:30 am + 3 hours = 2:30 pm.

AI explanation

The total time for the initial journey is 4.5 hours, so driving at 50 miles per hour gives a total distance of 225 miles. Traveling this distance at the new speed of 75 miles per hour takes 225 divided by 75, which equals 3 hours. Starting at 11:30 am and driving for 3 hours means she arrives at 2:30 pm.
