An electric immersion heater normally takes 83.0 min to bring cold water in a well-insulated container to a certain temperature, after which a thermostat switches the heater off. One day the line voltage is reduced by 7.00% because of a laboratory overload. How long does heating the water now take? Assume that the resistance of the heating element does not change.
