Mario is walking away from a motion detector at a rate of 1.5 feet per second. He started recording his distance from the motion

kipiarov [429]

Answer:

6 seconds

Step-by-step explanation:

Initial distance of Mario from motion detector = 2 ft

Speed of Mario = 1.5 ft/sec

Total distance of Mario from motion detector = 11 ft

Total distance moved by Mario while walking at the rate of 1.5 ft/sec = 11 - 2 = 9 ft

Given that:

Distance = 9 ft

Speed = 1.5 ft/sec

<em>Formula:</em>

$Distance = Speed \times Time$

$\Rightarrow 9 =1.5 \times Time\\\Rightarrow Time = \dfrac{9}{1.5}\\\Rightarrow Time = \bold{6\ sec}$

So, at <em>6 seconds</em>, Mario will be 11 ft from the motion detector.

<h3>Volume of the cylinder:</h3>

$v = \pi {r}^{2} h$

$v = 3.14 \times {2}^{2} \times 3$

$v = 37.68 \: {cm}^{3}$

<h3>Volume of the rectangular prism:</h3>

$v = lwh$

$v = 6 \times 5 \times 7$

$v = 210 \: {cm}^{3}$

<h3>Total volume:</h3>

$v = 37.68 + 210$

$v = 247.68 \: {cm}^{3}$
