Leaving at noon, how fast must you drive to get to the airport that is 30 miles away by 12:45pm?
Correct Answer
D. 40 mph
Explanation
To calculate the speed needed to reach the airport by 12:45pm, we need to determine the time available for travel. If we leave at noon and need to reach the airport in 45 minutes, we have 45 minutes to cover a distance of 30 miles. To convert the time to hours, we divide 45 minutes by 60, which gives us 0.75 hours. To calculate the speed, we divide the distance (30 miles) by the time (0.75 hours), which equals 40 mph. Therefore, driving at a speed of 40 mph is required to reach the airport by 12:45pm.
