18/60= 0.30 miles/ min
10 minutes 0.30*10=3 miles
Amount of flour used in bread recipe =
cups
Amount of flour used in muffin recipe =
cups
We have to determine how much more flour is in the recipe.
Since, more amount of flour is used in bread recipe than in muffin recipe.
Total amount of more flour = 
= 
= 
= 
Therefore,
more cup of flour is used in bread recipe than in muffin recipe.
Now, we will determine the total amount of flour used in both recipe.
Total amount of flour used in bread and muffin recipe
= 
= 
=
= 6 cups
Therefore, total 6 cups of flour are used in both the recipes.
To find the answer, we can first find the age of Rolando in four year:
17+4
=21
We can then proceed to find the current age of Marisa,which is 3/2 of Rolando’s age calculated above:
Let Marisa’s age be y.
3/2 y =21
y = 21 × 2/3
y = 42/3
y = 14
Therefore Marisa is currently 14 years old.
In three years, Marisa would be:
14+3
=17
Therefore, she will be 17 years old.
Hope it helps!
This is the work and the answer is 4/23 or (in decimal form) 0.17391304
