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
