Point of Equal Time (PET) = (Distance x Homeward Groundspeed) / (Outbound Groundspeed + Homeward Groundspeed)

TAS = 470 KTAS

Outbound Groundspeed = 470 + 55 knots Wind Component = 525 knots

Homeward Groundspeed = 470 - 75 knots Wind Component = 395 knots

PET = (D x H) / (O + H)

PET = (2,900 x 395) / (525 + 395)

PET = 1,145,500 / 920

PET = 1,245 NM (from Departure Point)

Outbound Groundspeed = 525 knots

Therefore, time to PET at 1,245 NM = 1,245 / 525 = 2.37 hours = 2 hours 22 minutes

14:35 + 02:22  = 16:57
