Answer:
[tex]Difference = \frac{13}{40}[/tex]
Step-by-step explanation:
Given
[tex]Thursday = \frac{3}{8}\ mile[/tex]
[tex]Tuesday = \frac{7}{10}\ mile[/tex]
Required
How much farther is she on Tuesday
To do this, we simply calculate the difference between distance covered on both days.
[tex]Difference = Tuesday-Thursday[/tex]
[tex]Difference = \frac{7}{10} - \frac{3}{8}[/tex]
Take LCM
[tex]Difference = \frac{28- 15}{40}[/tex]
[tex]Difference = \frac{13}{40}[/tex]
Hence, she ran 13/40 mile farther on Tuesday
