Answer:
6.1 s
Step-by-step explanation:
h = -16t² + 600
When the sack reaches the ground, h = 0.
0 = -16t² + 600
16t² = 600
t² = 600/16
t² = 37.5
t = 6.1 s
It will take 6.1 s for the sack to reach the ground.
Let X represent Karma's fathers age and Y represent Karma's age. The first term can be found using this formula:
Y = 1/3X → 5 Years ago
Y = 1/2X → 5 Years from now
From mental math, I can concur she's 15 and her father is 35. Then we plug in to check.
1/3(30) = 10 √ (Five years ago).
1/2(40) = 20 √ (Five years from current).
Their current ages are 15 and 35.
