Nina can ride her bike 63,360 feet in 3,400 seconds, and sophia can ride her bike 10 miles in 1 hour. what is nina's rate in miles per hour if there are 5,280 feet in a mile? which girl bikes faster?

convert feet to miles

63360/5280 = 12 miles

convert seconds to hours, there are 3600 seconds per hour

3400/3600 = 0.94 hours

since Nina rode 12 miles in 0.94 hours she is faster ( rode further in less time)

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
