Answer:

41.66 km/h

Explanation:

Calculate the distance of 1st travel :

v = d/t

25 km/h = d/1 h

d = 25 km/h × 1 h

  • d = 25 km

Calculate the distance of 2nd travel :

v = d/t

50 km/h = d/2 h

d = 50 km/h × 2 h

  • d = 100 km

Calculate the velocity of trip :

v = d/t

v = (25 + 100)/(1 + 2)

v = 125 km/3 h

  • v = 41.66 km/h

So, my velocity for the trip is 41.66 km/h
