Question

A helicopter dropped a package from a height of 900 ft above a stranded hiker. Use the formula t= √h/4 to find

many seconds it takes for the package to reach the hiker.

Answer 1

7.5 seconds

Explanation:

Using the formula

t =
`(√(h) )/(4)` ← substitute h = 900

t =
`(√(900) )/(4)` =
`(30)/(4)` = 7.5

Answer 2

15 seconds

Explanation:

Thinking process:

The time is given by the formula: t =
`\sqrt{(h)/(4) }`

The height h = 900

then the time is given by: t =
`\sqrt{(900)/(4) } \\= 15 seconds`
