Answer:

6 seconds.

Step-by-step explanation:

Given,

Matt starts 9 ft from a motion detector. He walks towards the motion detector at a constant rate of 1  1/2 feet per sec or 3/2 feet/sec.

We know that, s= vt  

here, s or distance is 9 feet and the constant velocity is 3/2 feet per second or 1.5 feet/sec.

According to the formula, t= s/v

Or, t= 9/ 1.5 = 6

So, Matt will take 6 seconds to reach the motion detector.
