Answer:

It took the cell phone 4.15 seconds to reach the ground

Step-by-step explanation:

The formula is  t=\frac{\sqrt{h}}{4} , where t is the time and h is the height

The height of that the cell phone dropped from it is 275 feet above the ground

∴ h = 275

- Substitute the value of h in the formula to find t

∵ t=\frac{\sqrt{275}}{4}

∴ t=\frac{5}{4}\sqrt{11}

- Change it to decimal

∴ t = 4.15 seconds to the nearest 2 decimal places

It took the cell phone 4.15 seconds to reach the ground
