An electric passenger train goes at 73 km/h in the direction of south east. A wind is blowing from the south at 31 km/h.

What is the direction that the smoke from the train is blowing and at what speed?

(In reply to Old Smokie by nellie)

In case it has a smoke - for waht ever reason - , I think the speed would be 53.75 km/h and angle would 69.06 from south
