Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
The town is having a race to see who can run around the town square 7 times the fastest. The town square is 3/4 of a mile long. The winner finishes the race in 42 minutes. Last year's winner finished in 47.25 minutes. How many minutes on average faster did this year's winner run one mile of the race compared to last year?

### Response:
The race is 5.25 miles long because 7 x .75 = <<7*.75=5.25>>5.25
They ran a mile in 8 minutes because 42 / 5.25 = <<42/5.25=8>>8
They ran 30 seconds per mile faster than last year's winner because 47.25 - 42 = <<47.25-42=5.25>>5.25
They ran 1/12 of a mile per second faster because 12 / 1 = <<12/1=12>>12
They ran 5 feet per second faster because 12 x 1/12 = <<12*1/12=1>>1
