Question

A trial 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.

Answer 1

I think so because she started at 2 1/4 then hiked to 4 3/8. That is roughly 2 miles and then from there she joked all the way back to 11/2

Answer 2

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.
