Question

Each day the workers drill down 22feet further until they hit a pool of water is at 110 feet, on which day will they hit the pool of water

Answer 1

$Given \: Depth \: the \: workers \: drill \: each$

$day = 22 \:feet \: --(1)$

$Depth \:of \: the \: water \: pool = 110 \:feet\: --(2)$

$Let \:number \: of \: days \: to \:hit \:the \:water$

$pool = n$

$\red {n} = \frac{ (2) }{(1)}$

$= \frac{110}{22}$

$= 5 \:days$

Therefore.,

$\green { On \: 5^{th} \:day \: they \:wiil \: hit }$

$\green { pool \:of \:water . }$

Answer 2

Given :

Each day the workers drill down 22feet further until they hit a pool of water is at 110 feet

To Find :

which day will they hit the pool of water

Solution :

Days taken to hit a pool of water = 110feet/22feet

⇒ Days taken to hit a pool of water = 110/22

⇒ Days taken to hit a pool of water = 5

★ on 5th days they hit the pool of water
