Kelsy is climbing up a mountain and will then climb down to a ledge on the side of the mountain. The ledge is 425 meters down when measured from the top of the mountain. If Kelsy has climbed a quarter of the way up the mountain and is currently at 125 meters, what will be her height above the ground when she is on the ledge?

Respuesta :

She is a quarter of the mountain, which is 125 meters. 125 x 4 is 500. the ledge is 425 feet down the mountain. 500 - 425 is 75. When she reaches the ledge, she will be 75 meters above ground.
