6. a bus travels 280 km south along a straight path with an average velocity of 88 km/h to the south. the bus stops for 24 min, then it travels 210 km south with an average velocity of 75 km/h to the south. a. how long does the total trip last? b. what is the average velocity for the total trip?

A-The trip is 6.38 hours long B-The average velocity would be 76.8 km/h

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
