Answer:
3 miles
Explanation:
The problem above is related to the topic on "Equivalent Ratios." In order to find the missing term in a proportion, you can use cross products.
Let n be the "missing term" or the number of miles that Bart Simpson can skateboard in 42 minutes.
=
- 4 x 42 = 56n
- 168 = 56n
= n- 3 = n
- n = 3 miles
Therefore, it takes 3 miles for Bart Simpson to skateboard in 42 minutes.
