On a cross-country trip, a couple drives 500 mi (miles) in 10h on the first day, and 400 mi in 8h on a second day. the average speed for the whole trip is:

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

1260=3*6*7*10=3^2*2^2*7*5 perfect cude = 3^3*2^
