i need some help with this question. "Jim is walking in a field and screams...the wall is 300 meters away it takes 1.7 seconds for the sound to come back.......wat is the temperature in the air." so i tried it as: V=d/t ....= 300m/0.85s ....= 353m/s from there i think i have to use the speed of sound formula and isolate the 0.59t. and then divide by it. i keep on getting a different answer then the one in my textbook.
