Question

$\text{Remo walked}\frac{17}{7}\text{miles and Lizy}$ $\text{walked}\frac{13}{7}miles.$
So, they walked miles in total.

• A. $\frac{4}{7}$
• B. $\frac{15}{7}$
• C. $\frac{30}{7}$
• D. $\frac{20}{7}$

Answer 1

The correct option is C $\frac{30}{7}$

$\text{Miles covered by Remo}=\frac{17}{7}$
$\text{Miles covered by Lizy}=\frac{13}{7}$

$\text{So, total distance}=\frac{17}{7}+\frac{13}{7}miles$

As the denominators of the fractions are the same, so the numerators can be added directly and denominator remains the same.

$=\frac{17+13}{7}$

$=\frac{30}{7}$

$\text{Hence, they have walked}\frac{30}{7}\text{miles in total.}$
