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?
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
