An object traveled a distance of 100 m in 10 s, what is the speed of the object?

[tex]\textsf{Given:}\begin{cases} \sf d = 100 \: m\\ \sf t = 10 \: s\\ \sf s = ?\\ \end{cases}[/tex]

[tex]\textsf{Formula:} \: \sf s = \frac{d}{t}[/tex]

[tex]\textsf{Solution:} \: \sf s = \frac{100 \: m}{10 \: s} = \underline{\sf 10 \: m/s}[/tex]

A car moved 500 m in 20 s, what is the speed of the car?

[tex]\textsf{Given:}\begin{cases} \sf d = 500 \: m\\ \sf t = 20 \: s\\ \sf s = ?\\ \end{cases}[/tex]

[tex]\textsf{Formula:} \: \sf s = \frac{d}{t}[/tex]

[tex]\textsf{Solution:} \: \sf s = \frac{500 \: m}{20 \: s} = \underline{\sf 25 \: m/s}[/tex]

A truck travels 110 miles in 2 hours. What is the average speed of the truck?

[tex]\textsf{Given:}\begin{cases} \sf d = 500 \: miles\\ \sf t = 2\: hrs\\ \sf s = ?\\ \end{cases}[/tex]

[tex]\textsf{Formula:} \: \sf s = \frac{d}{t}[/tex]

[tex]\textsf{Solution:} \: \sf s = \frac{110 \: miles}{2 \: hrs} = \underline{\sf 55 \: miles/hr}[/tex]

1.[tex]\huge\red{\boxed{\boxed{\sf\blue{10m/s}}}}[/tex]

[tex]\red{\boxed{\boxed{\sf\blue{s = \frac{100}{10} = 10}}}}[/tex]

=10m/s

2. [tex]\huge\red{\boxed{\boxed{\sf\blue{25m/s}}}}[/tex]

[tex]\red{\boxed{\boxed{\sf\blue{s = \frac{500}{20} = 25}}}}[/tex]

=25m/s

3. [tex]\huge\red{\boxed{\boxed{\sf\blue{55mi/h}}}}[/tex]

[tex]\red{\boxed{\boxed{\sf\blue{s = \frac{110}{2} = 55}}}}[/tex]

=55mi/h
