Question 349954: Problem: Hiking up a mountain, you notice that the air temperature drops 10 degrees celsius for every 1000 meters increase in elevation. Write a multiplication expression to represent the decrease in temperature if you hike up the mountain 3000 meters. Then evaluate the expression and explain its meaning.
This is a problem for my sixth grader's math homework and my wife and I are completely stumped. Neither of us can remember how to relate the temperature to the elevation in an equation and the lesson in the math book stops short of this type of problem (this particular problem is like a brain teaser at the end of the assignment). Can you help?

not exactly sure what the book is looking for...

k = 10�C / 1000m = .01�C/m

Td = 3000m * k ___ Td = 3000m * .01�C/m = 30�C

if you hike 3000m up the mountain , the temperature decreases 30�C

n=3000
n/1000 x -10
3000/1000 x -10= -30 So, with an altitude increase of 3000 meters, the temperature decreases by 30 degrees Celsius .
