Explanation:

planation:

Step1: Find common denominator

$\frac{3}{5} = \frac{6}{10}$

Step2: Subtract distances

$\frac{9}{10} - \frac{6}{10} = \frac{3}{10}$
---

Step1: Find common denominator

$\frac{5}{6} = \frac{10}{12}, \frac{3}{4} = \frac{9}{12}$

Step2: Subtract time values

$\frac{10}{12} - \frac{9}{12} = \frac{1}{12}$
---

Step1: Find common denominator

$\frac{1}{2} = \frac{5}{10}$

Step2: Subtract lengths

$\frac{9}{10} - \frac{5}{10} = \frac{4}{10} = \frac{2}{5}$
---

Step1: Find common denominator

$\frac{3}{4} = \frac{15}{20}, \frac{2}{5} = \frac{8}{20}$

Step2: Subtract distances

$\frac{15}{20} - \frac{8}{20} = \frac{7}{20}$

Answer:

1. $\frac{3}{10}$ mile
2. $\frac{1}{12}$ hour
3. $\frac{2}{5}$ foot
4. $\frac{7}{20}$ kilometer
