Answer:
A turtle travels about 90 feet
Because if a turtle can travel 450 feet within 25 minutes, then dividing 25 by 450 is 18 feet per minute, but if you multiply 5 minute x 18 feet, you get 90 feet in all.
So, a turtle can travel 450 feet per 25 minutes,
18 feet per minute, and
90 feet per 5 minutes
