A car is moving in 3 hours and 20 minutes and cover are distance of 300 km and other car is moving into hours and 80 minutes and cover are distance of 280km. What is the average speed. Give the value in kilometer per hour

Explanation

Car A:

  • Time = 3 hours 20 minutes = 3+
    3 + frac{20}{60} = 3.33     hours

  • Distance = 300 km

Car B:

  • Time = 2 hours 80 minutes = hours

  • Distance = 280 km

Total Distance


300 , text{km} + 280 , text{km} = 580 , text{km}

Total Time


3.33 + 3.33 = 6.66 , text{hours}

Average Speed Formula:


text{Average speed} = frac{text{Total Distance}}{text{Total Time}} = frac{580}{6.66} approx 87.09 , text{km/h}Total Time=580/ 6.66​≈87.09km/h
