Hey There,

This is a subtracting fractions problem.

Solutions-

1. <span>Convert $5 \frac{7}{10}$ to an improper question. You do this by multiplying the denominator and the whole number and adding that number to the numerator. The improper fraction would be $\frac{50}{7}$ </span>

2. Now, subtract $\frac{140}{0}- \frac{15}{10}$

3. The answer to step two should be $\frac{125}{10}$

Thus, the answer should be $\frac{125}{10}=12 \frac{1}{2}$

In conclusion, Jeff drives $12\frac{1}{2}$ miles farther then her sister.

Thank You!
