A 240 Volt, 60Hz supply has a heater and a single-phase motor connected in parallel to it. The heater draws a current of 5.5 amps and the total line current is 35 amps at a power factor of 0.60. The motor power factor is 0.484. By the way, the answer to this question is 0.484 (pf). I just can't figure on what to calculate to arrive at that answer.
