B 5 miles per hour per second
To find the approximate rate of change in miles per hour that Brooklyn's car accelerated, we need to calculate the change in miles per hour divided by the change in time. The car accelerated from 0 miles per hour to 75 miles per hour in 15 seconds.
The change in miles per hour is 75 - 0 = 75 miles per hour.
The change in time is 15 seconds.
Therefore, the approximate rate of change in miles per hour that Brooklyn's car accelerated is 75 miles per hour / 15 seconds = 5 miles per hour per second.
So, the correct answer is B) 5 miles per hour per second.
