Let's break down the information in the problem step by step:

• Team Rocket finished in 3.48 minutes.
• Team Jaguar finished in 3.471 minutes.
• Team Tortoise took twice as long as Team Jaguar.

To calculate the time for Team Tortoise:

Team Tortoise's time is twice that of Team Jaguar's. So, we need to multiply Team Jaguar's time by 2.

$\text{Team Tortoise's time} = 2 \times 3.471 = 6.942 \text{ minutes}$

Therefore, Team Tortoise took 6.942 minutes to finish the race.
