A temperature of t degrees Fahrenheit, sound travels s feet per second, where s= 21.9 square root 5t + 2457. During blasting for avalanche control in the mountains, sound traveled at a rate of 1117ft/sec. What was the temperature?
1117=21.9 square root 5t + 2457.
21.9 square root 5t=1117-2457
=-1340.
square root 5t =-1340/21.9=-61.18.
5t=3743.87.
t=748.77 Deg F.
