Answer: First option.
Step-by-step explanation:
To solve for "h" from the given the equation , you need to:
Apply the Subtraction property of equality and subtract to both sides of the equation.
Then you need to apply the Division property of equality and divide both sides of the equation by .
Then:
a)
the average speed, well it does 10 ft in 1.6 secs, so is simply their quotient, 10/1.6 = 6.25 ft/s on average.
b)
over the horizontal, well, it covered horizontally 9.25 ft in those 1.6 secs, so their quotient is 9.25/1.6 = 5.78125 ft/s on average.
c)
we don't know the vertical distance, but
so, it covered vertically about 3.8 ft in those 1.6 secs, so then 3.8/1.6 = 2.375 ft/s on average
