Akayaker travels x miles per hours downstream for 2 hours. on the 4 hour return trip, the kayaker travels 4 miles per hour slower. how far did the kayaker travel in total?

16

Step-by-step explanation:

one way=2x

one way=4(x-4)

2x=4(x-4)

2x=4x-16

2x=8

x=4

2 ways=2y=4x=16

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
