Answer:
23 Seconds
The roach is going 2 feet per second so you can split the amount of feet in half because he will go the same distance 2 times as fast.
1. We know that 30% expressed as a decimal is 0.30
Since 30% of people were using the internet, 0.30*3200 is our answer.
3200*0.30= 960.
Therefore 960 people were using the internet out of the 3200 surveyed.
