Answer:
1 1/8 mile
Explanation:
when it says altogether most of the time you're supposed to add.
When you add fractions you need to have both denominator (number below the line) be the same. and sense 1/2 and 4/8 are equal we will replace it.
you add the numerators (top numbers) and keep the denominator (bottom number)
Sense the numerator is bigger you subtract the bottom number from the top number and put a 1 in front of the fraction.
