In general, the air temperature decreases 12 degrees Fahrenheit for every 4,000 feet increase altitude. If a hiker climbs 3,000 feet, by how much can she expect the temperature to increase?

Respuesta :

9 degrees


because 12/4 = 3 degrees (per 1000 feet)
3 x 3 = 9 degrees total (in 3000 feet)

hope this helps
