The Walking Club is one of the after-school activities at Jefferson Middle School.
It consists of three groups of walkers. Each group walks at a different pace. All
groups begin together and walk the same 4-mile trail.
Wendy is new to the club. She asks each group how fast they walk. Each
group gives the answer in a different way. Find the speed of each group in
miles per hour
Group 1: We walk 25 miles per hour.
Group 2: We walk a mile in 20 minutes.
Group 3: We take 2 hours to walk the trail

You first need to know how much miles it takes on the trail. Then you look 20 x 3 is one hour. And if the 3 group said it takes 2 hours waking for them its like this, the first group takes one hour to go thru the trail, but the second group takes and hour and half the 3 group takes 2 hours.

I wish this helps. :)

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

the reporter's right

step-by-step explanation:

1/4 = .25 / 25%
