Answer:
approximately 300,000,000 meters per second
This process is:
<span>Distribute of the Negative Sign:
</span><span><span><span>5t</span>+t</span>−3</span>+<span><span>−1</span><span>(<span><span><span>7t</span>+5</span>−<span>(<span>8−<span>3t</span></span>)</span></span><span>)
</span></span></span><span><span><span><span><span><span><span>5t</span>+t</span>+</span>−3</span>+<span><span>−1</span><span>(<span>7t</span>)</span></span></span>+<span><span>(<span>−1</span>)</span><span>(5)</span></span></span>+<span><span>(<span>−1</span>)</span><span>(<span>−8</span>)</span></span></span>+<span><span>−1</span><span>(<span>3t</span>)</span></span>
<span><span><span><span><span><span><span><span><span><span>5t</span>+t</span>+</span>−3</span>+</span>−<span>7t</span></span>+</span>−5</span>+8</span>+</span>−<span>3<span>t
</span></span>Now simple, Just Combine Like Terms:
<span><span><span><span><span><span><span>5t</span>+t</span>+<span>−3</span></span>+<span>−<span>7t</span></span></span>+<span>−5</span></span>+8</span>+<span>−<span>3<span>t
</span></span></span></span><span>(<span><span><span><span>5t</span>+t</span>+<span>−<span>7t</span></span></span>+<span>−<span>3t</span></span></span>)</span>+<span>(<span><span><span>−3</span>+<span>−5</span></span>+8</span><span>)
</span></span>−<span>4<span>t
