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

### Instruction:
Bingo has two dogs. On average, they walk a total of 70 miles a week. The first dog walks an average of 2 miles a day. How many miles a day does the other dog average?

### Response:
70 miles / 7 days = <<70/7=10>>10 miles a day
The first dog walks 2 miles a day * 7 days = <<2*7=14>>14 miles in a week
70 - 14 = <<70-14=56>>56 miles
The other dog walks 56 miles in a week / 7 days = <<56/7=8>>8 miles a day.
