Sharon drove 270 miles in 4.5 hours. If she drove at a constant rate, how fast was Sharon driving?

Sharon was driving 60 miles per hour.

Step-by-step explanation:

To solve this you must divide both the amount of miles (270) and the amount of hours (4.5) by the amount of hours so that way you can see how many miles per hour you are going.

4.5 / 4.5 = 1

270 / 4.5 = 60

This means that Sharon was driving 60 miles per hour.

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.
