Doesn´t matter if it is time to sunset or time to running out of fuel...
Distance to Point of No Return =
(Fuel endurance (hours) × Ground speed return (knots) × Groundspeed outbound (knots)) / (Ground speed return (knots) + Groundspeed outbound (knots))
Correct answer: 97 nm

Given the time needed to accelerate to cruise TAS, to turn around and to decelerate and fly a circuit/an approach - the answer is probably 84nm ;)
