Answer 1

Answer:

Step-by-step explanation:

Given There are two paths that one can choose to  go from Sarah's house to James house. One  way is to take C street, and the other way  requires to take A street and then B street.  How much shorter is the direct path along C  street? (Using figure).

So choosing C street we get by Pythagoras theorem,

            = √2^2 + 1.5^2

            = √ 6.25

            = 2.5 miles.

If he chooses alternate way he has to cover 2 + 1.5 = 3.5 miles.

Now the difference between these two will be 3.5 – 2.5 = 1 mile.

Therefore by choosing the direct path he will be able to save 1 mile .
