A boat, which moves at 30 mi/h in still water, travels 3 mi downstream in the same amount of time that it takes to travel 2 mi upstream. Find the speed of the current.

step-by-step explanation:

-6 is the correct option from the above given options

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
