Mr. Earl E. Bird needs to arrive at work at exactly 8:00 AM. If he drives at an average speed of 50 miles per hour, he arrives 5 minutes late. If he drives at 70 miles per hour, he arrives 5 minutes early. Given the fuel efficiency of his car is better at 50 miles per hour than at 70 miles per hour, how many miles per hour does he need to drive to get to work exactly on time, considering he wants to use the higher of the two speeds for better fuel efficiency?
A) \( 55 \text{ miles per hour} \)
B) \( 60 \text{ miles per hour} \)
C) \( 65 \text{ miles per hour} \)
D) \( 70 \text{ miles per hour} \)
E) \( 75 \text{ miles per hour} \)
