function s/x)- 3600 ' gives a person's average speed in miles per hour if he or she travels one mile in The function s(x) = 60 + 04r 3600 (60+x) gives a person's average speed in miles per hour if he or she travels one mile in 3600(60 + x) x seconds more or less than 60 seconds. Use a linear approximation to s at 0 to find a person's approximate average speed if he or she travels one mile...
