Answer:
10. 4 mi
11. [tex]12\frac{11}{15}[/tex] mi
Step-by-step explanation:
10. To find the unit rate, divide the numbers.
[tex]68[/tex] ÷ [tex]17 = 4[/tex]
11. First, leave out the whole numbers and find the least common denominators (LCD), then add.
[tex]LCD=15[/tex]
[tex]\frac{2 *3}{5*3} + \frac{1*5}{3*5} = \frac{6}{15} +\frac{5}{15}[/tex] [tex]=\frac{11}{15}[/tex]
Now, add the whole numbers.
3 + 4 + 5 = 12
Include the whole number with the fraction.
[tex]12\frac{11}{15}[/tex]
