After 60 seconds of skiing, you will be 5,820 feet high.

Answer 1

To find the elevation level after skiing for 60 seconds using the linear model \( y = -30x + 6000 \):

1. Substitute \( x = 60 \) into the equation: \[ y = -30(60) + 6000 \]

2. Calculate: \[ y = -1800 + 6000 \] \[ y = 4200 \]

Therefore, after 60 seconds of skiing, you will be 4,200 feet high.
