Your school is 4 miles east and 1 mine south of your apartment there is a park 3 miles east and 4 miles south of your apartment
VMariaS [17]

Answer:

The distance between of the park to the school is approximately 8.6 miles

Step-by-step explanation:

The given information are;

The location of the school from the house = 4 miles East and 1 mile South

The location of the park from the house = 3 miles East and 4 mile South

By representing the direction East (x-direction) as being in the direction of vector \hat i and the direction South (negative y-direction)  as being in the direction of vector \hat j, we have;

The location of the school from the house = 4·\hat i + \hat j

The location of the park from the house = 3·\hat i + 4·\hat j

The distance, l, between the park and the school is given by the resultant of the two vectors as follows

l_x = 4·\hat i + 3·

l_y = \hat j + 4·

Therefore,

l = \sqrt{l_x^2 + l_y^2}  = \sqrt{7^2 + 5^2} = \sqrt{74} \approx 8.6 \ miles

The distance between of the park to the school ≈ 8.6 miles.
