    1. The problem statement, all variables and given/known data
    You see a neighbour in a cottage across the lake chopping wood. He is 2 km away and you see that it takes 2 s to hear each chop after you see it happen. Calculate the air temperature. (v= 332+ 0.6 T)

    2. Relevant equations


    3. The attempt at a solution
    v= 1 km/s
    0.6 T= 668 m/s
    T= 1113.3 ?

    With the numbers you have here, that would appear to be correct. Make sure that you include units on your Temperature for your solution. The equation you're using works and your logic is good. Double check your distances and times in the problem, as the problem doesn't seem "physical" as is, but if the distance is 2km and it is 2s difference, yes, you have the correct answer.
