they read about a new trail which is being constructed.it will be the park's longest at 11/2 miles. How much longer than the Blue Trail will it be?

11/2=3/2

no idea. How long is the Blue Trail?

To determine how much longer the new trail will be compared to the Blue Trail, we first need to know the length of the Blue Trail. Unfortunately, the length of the Blue Trail is not provided in the question. Therefore, without that information, we cannot directly calculate the difference in lengths between the two trails.

However, if you are given the length of the Blue Trail, you can subtract that length from 11/2 miles to find out how much longer the new trail will be.
