Answer
$87minutes$
Work Step by Step
The required time can be determined as follows:
$t=\frac{Q}{P}$
$\implies t=\frac{cm\Delta T}{P}$
$\implies t=\frac{\rho cV\Delta T}{P}$
We plug in the known values to obtain:
$t=\frac{1000(4190)(0.150)(41.6)}{5000}$
This simplifies to:
$t=5237.5s\approx 87minutes$
