Some questions on
standardized tests ask
you to choose a graph
th at best represents a
real-world situation.
Read th e question at the
right. Then follow the tips
to answ er it.TIP 1
Aiko's speed is
constant fo r most
of the race, so the
graph should be a
straight line most of
th e tim e.Aiko ra n at a co n stan t speed for m ost of a race. Toward
th e en d of th e race, she increased h e r speed until she
re ach e d th e finish line. W hich graph b est represents
Aiko’s distance traveled over time?CA>TIP 2
Aiko's speed increases
to w a rd th e end o f th e
race, so th e graph
should rise more quickly
at the end.Think I t Through
Choice A shows a constant
speed during the entire race.
Choice B shows an increasing
speed n e a r th e race’s end.
Choice C shows a complete
stop in th e middle of th e race.
Choice D shows a decreasing
sp eed n e a r th e race's end.
The correct answ er is B.dyjp Vocabulary Builder
