10. Which travels faster, a car that goes 200 miles in 2 hours, or a
umka21 [38]
<h2>Answer:</h2>

<em>Question 10. </em><u><em>The truck travels faster</em></u><em>.</em>

<em>Question 11. </em><u><em>The slug travels faster</em></u><em>.</em>

<h2>Step-by-step explanation:</h2>

<h2><u>Question 10.</u></h2>

<u />

<h3>1. Find the velocity of each vehicle.</h3>

Speed=\frac{distance}{time}

Speed_{Car} =\frac{200(miles)}{2(hours)}=100mi/h. \\\\ Speed_{Truck} =\frac{300(miles)}{2.5(hours)} =120mi/h.\\ \\

<h3>2. Compare the velocities.</h3>

Speed_{Car} =100mi/h < Speed_{Truck} =120mi/h.

<em>Hence, the trucks travels faster than the car.</em>

<em></em>

<u>-------------------------------------------------------------------------------------------------------</u>

<em></em>

<h2><u>Question 11.</u></h2>

<em>Apply the same method as in question 10.</em>

<h3>1. Find the velocity of each body.</h3>

<em />Speed_{snail}=\frac{20(cm)}{(3 min)} =6.67cm/min.\\ \\Speed_{slug}=\frac{15(cm)}{(2 min)} =7.5cm/min.

<h3>2. Compare the velocities.</h3>

Speed_{snail}=\frac{20(cm)}{(3 min)} =6.67cm/min < Speed_{slug}=\frac{15(cm)}{(2 min)} =7.5cm/min.

Hence, the slug travels faster.

Solve for y.<br><br> 6(y+4)=-3(2y-2) +8y<br><br> Simplify your answer as much as possible.<br> y =
nadezda [96]

Answer:

6(y + 4) = -3(2y - 2) + 8y

6y + 24 = -6y + 6 + 8y

6y + 24 = 2y + 6

Subtract -2y on both sides

4y + 24 = 6

Subtract -24 on both sides

4y = -18

y = - 4.5
