Answer 2

Hi there!

Let us consider the percent to be = x %

♦ 15 hours into seconds :-

15 × 60 × 60 = 54,000 seconds

ATQ,

x % of 54,000 seconds = 18

x / 100 × 54,000 = 18

x × 540 = 18

540x = 18

x = 18 / 540

x = 0.333333333 %

x = 0.33 %. ---( approx. )

Hence, The required percent is = x = 0.33 %

Hope it helps! :)
