The function s(x)=

gives a person's average speed in miles per hour if he or she travels one mile in 60+x seconds. use a linear approximation to s at 0 to find a person's approximate average speed if he or she travels one mile in 51 seconds. what is his or her exact speed?

the person's approximate average speed /hr

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
