Sam walked 15 ft. up a ramp and
discovered he was 9 ft. above the ground.
Pam walked an additional 20 ft. up the
ramp. How far above the ground is she
To find out how far above the ground Pam is, we need to add the height she walked to the height Sam was at.
First, let's find out Sam's final height above the ground. Sam walked 15 ft. up the ramp and was 9 ft. above the ground. So, his total height above the ground is 15 ft. + 9 ft. = 24 ft.
Next, we need to add the additional height that Pam walked. Pam walked 20 ft. up the ramp. Adding this to Sam's height, we get 24 ft. + 20 ft. = 44 ft.
Therefore, Pam is 44 ft. above the ground.
15/9 = 20/x
Cross multiply and solve for x.
15x = 180
x = 180/15 = 12
