$R = 0, 61 Ohm$ $R=0,61" Ohm"$

Explanation:

$I : electric current$ $I:"electric current"$
$R : Resistance$ $R:"Resistance"$
$t : time$ $t:"time"$
$P : Power$ $P:"Power"$
$Q : charge$ $Q:"charge"$
$I=(Delta Q)/(Delta t)$
$I=25/4 "A"$
$P=I^2*R$
$24=(25/4)^2*R$

$24=625/16*R$
$R=(24*16)/625$

$R=0,61" Ohm"$
