Fred: 4m: 30 minutes=8 miles per hour
janet: 6m: 40minutes= 3 miles every 20 minutes=9 miles per hour
so janet runs 1 mile more per hour
filled in:
Fred ran 4 miles in 30 minutes. Janet ran 6 miles in 40 minutes. Fred and Janet each continue running at their same rate for 1 hour. fred will run 8 miles in 1 hour. Janet will run 9 miles in 1 hour. Janet will run 1 miles farther in 1 hour
