so if a car was moving 40km/hr, it means in 1 hour, the car will travel 40km. Since the car goes for 2 hours, the car will have traveled for 80 miles. Same.for the car going 55km/hr for 2 hours. 55 times 2 is 110km. 110 + 80 = 190km total. You can find the average velocity by by the distance traveled divided by how much time elapsed. so 190 divided by 4 is 47.5. So the distance traveled is 190km, and the average velocity is 47.5

Total distance cover by car is 190 km

Average velocity is 47.5 km/h

Explanation:

Given:

Speed of car is 40 km/h for 2 hour

Speed of car is 55 km/h for 2 hour

Find:

Total distance cover by car

Average velocity

Computation:

Distance = Speed × Time

Distance D1 = 40 × 2

Distance D1 = 80 km

Distance D2 = 55 × 2

Distance D2 = 110 km

Total distance cover by car = D1 + D2

Total distance cover by car = 80 + 110

Total distance cover by car = 190 km

Average velocity = Total distance cover by car / Total time taken

Average velocity = 190 / (2+2)

Average velocity = 190 / 4

Average velocity = 47.5 km/h
