Question 154740: I need help. I got as far as +5=+sqrt+%28d%2F16%29+
Please help me solve this equation: The distance d (in feet) that an object will fall in t seconds is given by the formula +t=+sqrt+%28d%2F16%29 To find the height of a bridge above a river, a man drops a stone into the water. If it takes the stone 5 seconds to hit the water, how high is the bridge?

I got as far as +5=+sqrt+%28d%2F16%29+
----------
Square both sides:
25 = d/16
d = 400 feet
This is more often shown as d = 16t^2.
