Question

Due to global warming, over a 20-year period, many birds have extended the northern margins of

their ranges by an average of about 12 miles. Assuming global warming continues at the same
rate, by how many miles will they have extended their range in another 10 years?

Answer 1

I’m pretty sure it’s 16 miles.
12 divided by 2 is 6
So in another 10 years, they would have extended their range by 6 more miles in 10 years.
So 30 years would be 16 miles.
Hopefully this helps!
