Answer 2

Answer:

15 Seconds

Step-by-step explanation:

Let the no. of seconds be $x$

⇒ $\frac{x}{1 Hour}$ * 100 = 25%

⇒ $\frac{x}{60 Seconds}$ * 100 = 25%

⇒ $\frac{x}{60}$ * 100 = 25%

⇒ $\frac{x}{3}$ * 5 = 25%

⇒ $\frac{x}{3}$ = $\frac{25}{5}$

⇒ $\frac{x}{3}$ = 5

⇒ $x$ = 5 * 3

⇒ $x$ = 15

Therefore 25% of 1hour = 15 seconds
