So, the first thing you want to find out is how many seconds each person adds to the wait time. Find out how many seconds are in 20 minutes.. 20*60=120. 120/150=0.8 seconds. Each person adds 0.8 seconds to the wait time. Now, multiply that by 240.. 240*0.8=192 seconds. Lastly, find out how many minutes 192 seconds is... 192/60=32 minutes.
I hope I did that right! And if I did, I hope that helped!
Gradient =2 because the slope is 2 units. Y-intercept = -2 because it crosses the y-line at -2.
Answer: The slope of p is 1/3
Step-by-step explanation:
If the lines are perpendicular, this means they are opposite.
Thus, O is opposite P and since O = -3, P = 1/3
34 = 2x +8x + 8(3)
34 = 2x + 8x + 24
34 = 10x + 24
10 = 10x
<em><u>x = 1</u></em>
