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

### Instruction:
 Colin can skip at six times the speed that Brandon can.  Brandon can skip at one-third the speed that Tony can.  And Tony can skip at twice the speed that Bruce can.  At what speed, in miles per hour, can Colin skip if Bruce skips at 1 mile per hour?


### Response:
 Soit B la vitesse de Bruce.
La vitesse de Tony est de 2B.
La vitesse de Brandon est de (1/3)2B = (2/3)B.
La vitesse de Colin est de 6(2/3)B = (4/3)2B = (8/3)B.
Ainsi, Colin saute à une vitesse de 2 2/3 miles par heure.
