Two rockets are launched from the ground at the same time. the height of rocket a in feet is modeled by

h(t)= -16t^2 + 128t

where t is the time in seconds after the launch. the height of rocket b in feet is shown in the graph.

which statement is true?

a. rocket a is in the air for about 2.75 s longer than rocket b

b. rocket a is in the air for about 10.75 s longer than rocket b

c. rocket b is in the air for about 2.75 s longer than rocket a

d. rocket b is in the air for about 10.75 s longer than rocket a
