(PLEASE HURRY! EXTRA POINTS!)

Two students created models of the same building. One student used a scale factor of 3 centimeters (cm) = 15 meters (m). The
second student used a scale factor of 4.5 = 15 m. The height of the original building is 20 meters. What is the difference between the heights of the two students’ models?

A. 1.5 cm
B. 6.5 cm
C. 33 cm
D. 2 cm

Answer 1

Answer:

im pretty sure its A. 1.5cm

Step-by-step explanation:

Answer 2

Answer:

D

Step-by-step explanation:

Lets find the rate of centimeters to meters.

3 / 15 = 0.2cm per m

4.5 / 15 = 0.3cm per m

Multiply to find the height in cm of the model.

0.2 * 20 = 4cm

0.3 * 20 = 6cm

Subtract to find the distance.

6 - 4 = 2cm

Best of Luck!
