Dan rode 7/12 miles farther than walk after school.
<h3>What is a fraction?</h3>
Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English.
To compare both the fractions we will make the denominators similar and then subtract them to know the distance.
So the walking distance is 1/3 miles
This is also equal to 4/12 miles. (By multiplying both denominator and numerator with 4)
Now subtract 11/12 and 4/12
11/12-4/12 = 7/12 miles.
Therefore, Dan rode 7/12 miles farther than walk after school.

Answer:
Savannah's age = 6 years
Step-by-step explanation:
Let
Savannah's age = x
Dylan's age = 15
Dylan is 15, which is 3 years older than twice his sister Savannah’s age
Dylan = 2x + 3
Find Savannah's age
2x + 3 = 15
Subtract 3 from both sides
2x + 3 - 3 = 15 - 3
2x = 12
Divide both sides by 2
2x / 2 = 12 / 2
x = 6
Therefore,
Savannah's age = x
= 6 years
Dylan's age = 2x +3
= 2*6 + 3
= 12 + 3
= 15 years
