Answer:
Darnell can run 1100 yards in 6 minutes
Step-by-step explanation:
There are 2 ways you can solve this
Method 1: You would have to divide 550 by 3 which you would get about 183, (the exact answer is very long so I recommend using a calculator). Then you multiply that by 6 to get 1100.
Method 2: This one would probably be easier. Since 3 x 2 is 6 then you can multiply 550 x 2 to get 1100.
I hope this helps!
