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

### Instruction:
Dale owns 4 sports cars. The red one can travel at twice the speed of the green one, but the green one can travel at 8 times the speed of the blue one.  The yellow one is broken and cannot move at all.  If the blue one can travel at a speed of 80 miles per hour, at what speed, in miles per hour, can the red car travel?

### Response:
If the blue car can travel at 80 mph, then the green one can travel at 8*80=<<80*8=640>>640 mph
If the green car can travel at 640 mph, then the red can travel at 2*640=1280 mph
