Answer 2

• This question can be easily solved by using Ratio and Proportion Chapter formula. So we are Given that : The fastest elevators in the Burj Khalifa can travel 330 feet in just 10 seconds and we are asked To Find : How far does the elevator travel in 11 seconds. Let the height the elevator travel in 11 seconds be 'A'

$\sf{\dashrightarrow 330:10::A:11}$

$\sf{\dashrightarrow 330\times 11 = 10\times A}$   --- [Since Product of means = Product of Extremes]

$\sf{\dashrightarrow 3630 = 10A}$

$\sf{\dashrightarrow A=3630/10=363}$
