Final answer:
To find the total distance Don traveled, add 1/3 of a mile (bike riding) to 1/4 of a mile (walking), which results in 7/12 of a mile. The correct answer is (c) 7/12 mile.
Step-by-step explanation:
When Don rode his bike for 1/3 of a mile and then walked 1/4 of a mile, to find out the total distance he traveled, we need to add these two distances together. The calculation would be as follows:
- Add the fractions: ¼ + ⅓ = ⅜ + ⅙
- Find a common denominator, which in this case is 12, so we convert the fractions: ⅓ = 4/12 and ¼ = 3/12.
- Add the converted fractions: 4/12 + 3/12 = 7/12.
The total distance Don traveled is 7/12 of a mile, which means the correct answer is (c) 7/12 mile.
