A bus travels 290 km south along a straight path with an average velocity of 81 km/h to the south. The bus stops for 25 min, then it travels 210 km south with an average velocity of 80 km/h to the south. How Long does it lasts ? Answer in units of h . What is the average velocity for the total trip? Answer in units of km/h
Answered by Henry
a. T=290km/81km/h + 210km/80km/h + 25/60 = 6.62 h.

b. V = d/T = (290+210)/6.62 = 75.5 km/h.
