In March, Bill ran an average of 1 mile an hour. If by June he had increased his pace by 10 seconds per mile, then which of the following expresses the number of hours it would take Bill to complete one mile in June?	Choices:
A) 3590/60^2
B) 2410/60^2
C) 2390/60^2
D) 3586/60
E) 60^2/3590

3600 seconds.   If he increases his speed by 10 seconds, he will complete a mile in 3590 seconds. Converting in hours= 3590/(60 * 60) = 3590/(60^2)   3590/60^2NSWER: 3590/60^2
