Answer:
2.16 s
Step-by-step explanation:
When it hits the ground, height h=0 hence



Using quadratic formula

Since time can't be negative, 
t=2.16 s
<span>Which one is closer to 41/50, 9/11 or 10/11
=> Let’s find the value of the two given choices to be able to fin which one
is closer to 41/50
=> 9/11 convert this to decimal number
=> 9 divide by 11
=> 0.82
=> 10/11 convert in decimals
=> 10 divide by 11
=> 0.91
Now, we have the value of both numbers, let’s find the value of 41/50
=> 41/50
=> 41 divided by 50
=> 0.82
Thus, the closer number to 41/50 is the 9/11 because they both have 0.82
decimal value.
