Answer:
0.6 seconds to 2.6 seconds
Step-by-step explanation:
From the graph the ball reaches 28 feet after 0.574 seconds
and doesn't fall below that until 2.614 seconds
0.574 rounded is 0.6 seconds
2.614 rounded is 2.6 seconds
Let n be unknown number, then 1/5 of this number is 1/5n. When you add these two numbers, you get
You know that this sum is equal to 24, so
