Answer:
3 3/8 seconds.
Step-by-step explanation:
When it reaches the ground h = 0 so:
54t - 16t^2 = 0
16t^2 - 54t = 0
2t(8t - 27) = 0
t = 0 or t = 27/8 (we ignore the t = 0 ) so:
t = 3 3/8 seconds.
If you mean each minute she read 3 pages.
If she started on page 20 and read 3 pages every minute, and the answer is how many pages did she read in 9 minutes.
Simple just do 20 x 9.
First step - what’s 2 x 9...18. Now anytime there’s a zero just simplify it by putting the 0 at the end of your answer. So the answer would be 180.
I hope this helped!!!
