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

[shivang_phy]

it is assumed that the a/c does nor do all of those thing when questions like these are made....correct ans 97...

[yash]

yes the correct answer in 97 kts
