A turtle crawled 21 meters in 12 minutes. How long did it take her to crawl 14 meters if she crawled at the same rate the whole time????
21÷12= 1.75 meters per min so 14÷ by 1.75 is 8 min correct. Or am I way off if so please explain

Reiny
21 metres in 12 minutes
> 1 metre in 12/21 or 4/7 minutes
so in 14 metres  14(4/7) minutes = 8 minutes
You are correct
or, you could just set up a simple proportion:
12/21 = x/14
21x = 168
x = 168/21 = 8
