The jones family is driving from san antonio, texas, to anchorage, alaska, which is a distance of 4304 miles. they have already driven 1639.271 miles. how much farther does the family need to drive to reach anchorage?

We know that Jones family is driving from San Antonio to Anchorage, and that the distance between these two places is 4,304 miles.

Distance already covered by the family  = 1,639.271 miles

Distance left to be covered = Total distance - Distance already covered

⇒ Distance left to be covered = 4,304 - 1,639.271

⇒ Distance left to be covered = 2,664.729 miles

Hence, the family needs to drive 2,664.729 miles further to reach Anchorage.

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
