Question

To get to his parents’ house, Ruben would have to drive due north 12 miles. To get to his grandparents’ house, he would have to drive due east 9 miles. What is the distance between the parents’ and grandparents’ houses?

Answer 1

d = 15 miles

Explanation:

To get to his parents’ house, Ruben would have to drive due north 12 miles.

To get to his grandparents’ house, he would have to drive due east 9 miles.

It is required to find the distance between the parents’ and grandparents’ houses.

First distance is 12 miles and second distance is 9 miles.

So,

`d=√(12^2+9^2) \\\\d=15\ \text{miles}`

So, the distance between the parents’ and grandparents’ houses is 15 miles.
