Final answer:
Joshua rode 2 miles from home to the park and 1 mile from the park to the store, totaling 3 miles for the entire trip from home to the store.
Step-by-step explanation:
The question involves simple arithmetic to calculate the total distance Joshua rode his bike by adding the two distances given. From home to the park, he rode 2 miles, and from the park to the store, he continued for another 1 mile.
To find out how far he rode from his home to the store, we add these two distances together:
Distance from home to park: 2 miles
Distance from park to store: 1 mile
Total distance: 2 miles + 1 mile = 3 miles
Therefore, the correct answer is 3 miles, which corresponds to option C.
