math homework

I need help with a 6th grade math problem =) Hiking up a mountain, you notice that the air temp drops10degrees C for every 1,000 meters incresing in elevation.


 


Write a multiplication expression to represent the descrease in temp if you hike up the mountain 3,000 meters.



TIA girls...this is sad lol

10/1000 = x/3000


it's a question about ratios

yeah it would be if 10 degrees drops every 1000 feet--> 10/1000


then how much decrease in 3000 feet right?


so 10/1000 on left side of "="


then x/3000 ---> b/c you dont know the decrease for the 3000 feet, you only know the elevation


10/1000 = x/3000 ---> b/c you are cross multiplying to find the "x"


x=30

I thought it was simply 10 x 3


10 for the amount the temp changes for every thousand feet and 3 for the "3,000" feet hiked.


I don't know...I'm much better with fractions and anything to do with a tape measure :)


Good luck :)
