But you are given 
and need to determine 
Multiply both sides by 
Take the square root of both sides:
.
Discard the negative root; the idea of negative time in this context being an absurdity.
To obtain your specific answer, substitute the given value for and then do the required arithmetic.
By the way, that is an unbelievably tall tree. I say unbelievably because "Lost Monarch," the tallest of the California Coastal Redwoods and said to be the world's tallest tree is approximately 320 feet tall measured from the ground.
