Lucas Is carrying his rock collection into class. He carries 30 pounds of rare rocks 15 feet Into Classroom 6. It takes him
3 minutes to get them into the classroom. What Is Lucas's speed and how much work is done? Be sure to show your
work with equations as part of your answer.

Answers

Answer 1

12mph

Step-by-step explanation:

180 divided by 15 is 12

speed = time ÷ distance

Answer 2

ANSWER: speed = 5

work = 450

EXPLANATION:  

Before starting to figure out this equation we must get rid of all the unneeded information. Here is a problem, Lucas is carrying his rock collection into class. He carries 30 pounds of rare rocks 15 feet into Classroom 6. It takes him 3 minutes to get them into the classroom. What is Lucas's speed and how much work is done? The unneeded information is highlighted. Now we can begin! First we must figure out Lucas speed. The equation for speed is,

Speed = distance / time. The distance is 15 feet and the time is 3 minutes. 15 / 3 = 5. Now we must figure out how much work is done. The equation for work is:  Work = force x distance.  The force in this equation is 30 lb And the distance is 15 ft. 30 x 15 = 450

Answers

Answer:

Step-by-step explanation:

Adjacent angles of parallelogram are supplementary.

∠A + ∠D = 180

Divide both sides by 2

[tex]\frac{1}{2}[/tex] ∠A + [tex]\frac{1}{2}[/tex] ∠D = 90

∠PAD + ∠ADP = 90       --------------------(I)

IN ΔPAD,

∠PAD + ∠ADP + ∠APD = 180 {angle sum property of triangle}

90  + ∠APD = 180         {from (I)}

          ∠APD = 180 - 90

         ∠APD = 90

∠SPQ = ∠APD             {vertically opposite angles}

∠SPQ = 90°

Similarly, we can prove ∠PQR = 90° ; ∠QRS = 90° and ∠RSP = 90°

In a quadrilateral if each angle is 90°, then it is a rectangle.

PQRS is a rectangle.
