To find H and O use CRP5 or similar:

Centre dot on TAS, 180 kts, rotate to wind direction, 045°; come down from centre dot for wind speed, 50 kts; mark end of wind vector at 130 kts.

Rotate to outbound track under heading index; note drift 14°Stbd; rotate track to drift; note drift now 11°Stbd; rotate track to drift; note drift still 11°Stbd. Required heading outbound will be 079° to track 090°; groundspeed out, O = 141 kts

Rotate to homebound track under heading index; note drift 9°Port; rotate track to drift; note drift now 11°Port; rotate track to drift; note drift still 11°Port. Required heading homebound will be 281° to track 270°; groundspeed home, H = 212 kts

Time to fly out = (1 x 212)/(141 + 212) = 0.6 hr at outbound groundspeed = 85 nm
