problem:

At the top, Mount everest has an altitude of 8848m.

Mountain climbers arrive at a base camp on the mountain.

The base camp is at an altitude of 4700m where the temperature is 4 degress celsius.

Meterologists have found the folllowing relationship between altitude and temperature:

*the temperature drops 2 degrees celsius for every 300m increse in altitude.

What is the temperature at the top of mount everest?

---------------

so far my guess is .. you subtract 8848-4700=4148.. and then divide that my 300m .. and with that you multiply it by 2 .. ?

please help moi

thanks!
