Question

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​

Answer 1

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. :)
