Question

Three friends decided to connect their individual car batteries in parallel using ideal cables (negligible resistance) to power up the car of their fourth stranded friend as shown in this circuit. Unknown to them, their batteries are not fully charged and have different series resistance values and voltages as indicated. The starter motor of the fourth friend's car has an effective resistance of 0.185 ohms.

How much current will be supplied by their parallel combination to the starter motor of the car and what is the Thevenin voltage of the parallel combination as seen by the starter motor element M?
