Question

The distance between R and T on the coordinate grid is ___ units. (Input whole numbers only.)

Answer 1

45 units is the answer

Answer 2

Answer:  the distance between the points R and T is 45 units.

Step-by-step explanation:  We are given to find the distance between the points R and T on the co-ordinate grid.

Distance Formula : The distance between the points (a, b) and (c, d) i given by

$D=\sqrt{(c-a)^2+(d-b)^2}.$

From the co-ordinate grid, we note that the co-ordinates of point R are (-30, 10) and the co-ordinates of point T are (15, 10).

Therefore, the distance between the points R and T is given by

$D=\sqrt{(15-(-30)^2+(10-10)^2)}=\sqrt{45^2+0^2}=\sqrt{45^2}=45.$

Thus, the distance bewteen the points R and T is 45 units.
