Can you post the graph?

OpenStudy (futureboy1):

i think its 150 feet

OpenStudy (anonymous):

no

OpenStudy (futureboy1):

why not

OpenStudy (welshfella):

follow the vertical line form t = 10 and see where it cuts the graph

OpenStudy (anonymous):

140

OpenStudy (anonymous):

When the x-value is 10, what is the y-value? Look:

|dw:1449337517230:dw|

OpenStudy (welshfella):

X is the mileage

OpenStudy (futureboy1):

think about it at 10 seconds reaches 140 feet so another second it would have reached 150 feet

OpenStudy (anonymous):

140 is your answer

OpenStudy (anonymous):

I see. "After 10 seconds" doesn't mean "11 seconds," it means "10 after 0."

OpenStudy (welshfella):

- you want the mileage at t = 10 not t = 11

OpenStudy (futureboy1):

OpenStudy (anonymous):

OpenStudy (anonymous):

thanks
