S If it takes someone t minutes to drive, run, or walk a mile, then their average speed s(t), in miles per hour, is
given by the formula
60
s(t) = 0
for t > 0
t
Find s(10) and s(12).
s(10) =
s(12) =
miles per hour
miles per hour

seems like d

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
