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.

(180 - 52) \div 2 = 128 \div 2 = 64


so D is 26:
180 - (90 + 64) = 180 - 154  \\  = 126
