Step 1.1

Substitute

$12262.5 J$ for

$W$ .

$P = \frac{12262.5 J}{t}$

Step 1.2

Substitute

$5 s$ for

$t$ .

$P = \frac{12262.5 J}{5 s}$

$P = \frac{12262.5 J}{5.00 s}$

Step 2

Step 2.2.1

Cancel

$s$ .

$P = \frac{12262.5 (W s)}{5.00 s}$

Step 2.2.2

Rewrite the expression.

$P = \frac{12262.5 (W)}{5.00}$

$P = \frac{12262.5 (W)}{5.00}$

Step 2.3

Rewrite the expression.

$P = 2452.5 \frac{1 W}{1}$

Step 2.4

Combine fractions.

$P = 2452.5 W$

$P = 2452.5 W$

Step 3

Round to

$3$ significant figures.

$P = 2.45 \cdot 10^{3} W$
