Question

Please help me with this i really need it, thank you!

Each gridline represents one mile. If Ryan drove from home to the soccer field and then from the soccer field to the library, traveling in a straight line to each destination, he would have traveled ___ miles by the time he reached the library.

Answer 1

13 miles

The soccer field is 5 miles from home in a straight line (=sr(3^2 + 4^2))
Plus the 8 miles to the library

Answer 2

13 miles

Explanation:

the distance from the soccer field to the library is 8 miles

the distance between home and soccer field is a hypotenuse, use Pythagorean theorem to find the distance.

`a^2+b^2=c^2\\\\4^2+3^2=c^2\\\\16+9=c^2\\\\c^2=25\\\\c=5`

the distance is 5 miles

5 + 8 = 13 miles total
