Answer:
B : 0.7
Explanation:
Given:
Doug lives 7. Block away from his school.
Each block is about 265 feet long.
Question asked:
What is total round-trip distance,in miles that Doug walks to and from school each day ?
Solution:
Each block is about = 265 feet
7 Block =
![265*7 = 1855 \ feet](https://img.qammunity.org/2021/formulas/mathematics/high-school/p3wey1hz6yeppct2egmu4atzewbh9kw7zt.png)
As he lives 7 block away from his school that means his round trip distance is,
7 block ( travel during going to school ) + 7 block ( when return from school )
Therefore, his total round trip is 14 block, means 1855 feet + 1855 feet = 3710 feet.
Now, we have to convert it into miles as here asked: (unitary method)
5280 feet = 1 mile
1 feet =
![(1)/(5280)](https://img.qammunity.org/2021/formulas/mathematics/high-school/lros3t84x0a4j8vpw7xgb8e4ve4igl31gq.png)
3710 feet =
![(1)/(5280)*3710](https://img.qammunity.org/2021/formulas/mathematics/high-school/134me2qa7xei1idntoc5s6ed4i8n771hg4.png)
=
![(3710)/(5280) = 0.7 \ miles](https://img.qammunity.org/2021/formulas/mathematics/high-school/ud332z4t1crq8c6d8icefbsdhdezilu557.png)
Thus, total round-trip distance,in miles that Doug walks to and from school each day is 0.7 miles.
