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.

how long does the total trip last?
what is the average velocity for the total trip?

  • Physics - ,

    280km / 88km per hour = 3.18 hours

    +

    24 minutes = .4 hours

    +

    210km / 75km per hour = 2.8 hours

    2.8 hours + .4 hours + 3.18 hours = 6.38 hours

    Average Velocity = Total Distance / time

    Total distance = 280 + 210 = 490km

    490km/6.38hours =76.8km per hour
