<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.

1) c= 3.5cm × 22/7

c= 77cm/7 = 11cm

2) c= 2×3.14×5cm

= 6.28× 5cm

=31.4cm

3) L=180/360 × 22/7 × 3cm

= 1/2 × 22/7 ×3cm

=4.71 cm

4) c=12cm ×3.14

=37.68cm

5) c = 4.5cm × 3.14

=14.13cm

6) c = 6.7cm × 3.14

= 21.038cm
