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? Let's think step by step and output the final answer after "####".

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