Answer :
No beause 5+8+4=17 and 17> 15 by 2. So they can carry it 17 feet with each person taking 1 turn. Hope I helped!
Let
x--------> distance that Kerry can carry the basket in feet
y--------> distance that Rachel can carry the basket in feet
z-------> distance that Daniel can carry the basket in feet
we know that
[tex] x=5\ ft[/tex] -------> equation [tex] 1 [/tex]
[tex] y=x+3[/tex] -------> equation [tex] 2 [/tex]
[tex] z=(y/2)[/tex] -------> equation [tex] 3 [/tex]
Substitute equation [tex] 1 [/tex] in equation [tex] 2 [/tex]
[tex] y=5+3[/tex]
[tex] y=8\ ft[/tex]
Find the value of z
[tex] z=(8/2)=4\ ft[/tex]
if each person taking only one turn,
then
the distance that they can carry the basket is equal to ------> x+y+z
[tex] (5+8+4)=17\ feet[/tex]
[tex] 17\ feet > 15 \ feet[/tex]
therefore
the answer is
Yes It is reasonable
