What's the air temperature when Δd=250m

  • #1

Homework Statement



A hunter wanted to know the air temperature. The echo from a nearby cliff returned 1.5 s after he fired his riffle. If the cliff is 250 m away, how do you calculate the air temperature?

Homework Equations



v=331 m/s + (0.59 m/s/c˚)T niSinθi=nRSinθR x=Δd/2 These eq'ns might be useful

The Attempt at a Solution



x=250 m/2 = 125
v=125 m/1.5s = 83.33 m/s
83.33 m/s = 331 m/s + (0.59 m/s/c˚)T

why you used x = 125??

what is the distance travelled by sound wave in the whole process????
