If Julie ran 3.6 miles from home to the gym and then walked 0.7 miles to the store, she then ran from the store back home. If her total distance covered after she returned from the store was 7.2 miles, how far is it from the store to her home?
Write and simplify an expression that would represent the distance she covered.
Answer (2)
So,
Home ---- gym = 3.6 mi. gym ---- store = .7 mi. store ----- home = x
3.6 + .7 + x = 7.2 mi.

4.3 + x = 7.2
Subtract 4.3 from both sides x = 2.9
The distance from the store to her home is 2.9 miles.
The distance from the store to Julie's home is 2.9 miles, which can be calculated by setting up a simple equation based on the distances she ran and walked. By summing the distances and solving for the unknown, we find it straightforward to determine this distance. Therefore, Julie ran 2.9 miles back home from the store.
