Avalanches occur at 245 miles per hour. 245 miles per hour is 4 times faster than the fastest downhill skier. What is the speed of the fastest downhill skier rounded to the nearest mph?

61 mph is the fastest skiers speed.

Step-by-step explanation:

Start with what is given and convert it to an equation.

245 is 4 times faster than the skiers (unknown) speed.

245 = 4x     Divide both sides by 4

245/4 = x

61.25 = x    Round to nearest mph means whole number of miles .25 <.5 so Round down to 61 mph

560

hope this : )

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
