Atrial has markers every 1/8 mile. jody starts at the 2 1/4-mile marker, hikes to the 4 3/8-mile marker, and then hikes back to the 1 1/2 mile marker. did jody hike more than 4 miles? explain.

1) determine how many miles Jody hikes when she leaves from the 2 1/4 mile marker and arrives at the 4 3/8 mile marker, by subtraction:

4 3/8 - 2 2/8 = 2 1/8 miles.

2) determine how many miles she hikes, leaving the 4 3/8 mile marker and arriving at the 1 1/2 mile marker.  Again, subtract:

4 3/8 - 1 4/8 =   3 11/8 - 1 4/8 = 2 7/8 miles.

Adding together 2 1/8 miles and 2 7/8 miles, we get 5 miles.

Did Jody hike more than 4 miles?  You decide.
