Answer: 3 Miles

54 / 4 = He's going one mile every 14 minutes. Use unit rates i.e 1 mile for every 14 minutes to figure out that he would skate 3 miles in 42 minutes.

Answer:

3 miles

Step-by-step 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.

  • [tex]\frac{4 miles}{56 min.}[/tex] = [tex]\frac{n}{42 min.}[/tex]
  • 4 x 42 = 56n
  • 168 = 56n
  • [tex]\frac{168}{56}[/tex] = n
  • 3 = n
  • n = 3 miles

Therefore, it takes 3 miles for Bart Simpson to skateboard in 42 minutes.
