Answer:
T1 + T2 = 3.5 : T1 time for the rock to reach bottom of well and T2 time for the sound to reach the top of the well.
16 * T12 = 1087 * T2 : same distance which the height of the well.
T2 = 3.5 - T1 : solve for T2
16 * T12 = 1087 * (3.5 - T1)
T1 = 3.34 seconds
Height = 16 * (3.34)2 = 178 feet (to the nearest unit)
Step-by-step explanation:
178 feet
