The first 2 hours the car moved at an average speed of 30 km / h. the next hour he stood still and then 3 hours

The first 2 hours the car moved at an average speed of 30 km / h. the next hour he stood still and then 3 hours moved at an average speed of 60 km / h. Determinant of the average speed of the vehicle for the entire journey.

1. Determine how many kilometers the car drove at the first speed:
30 x 2 = 60 km;
2. Determine how many kilometers the car traveled at the second speed:
60 x 3 = 180 km;
3. Determine the total distance that the car has traveled:
60 + 180 = 240 km;
4. Determine the total time of movement of the car, taking into account the stop:
2 + 1 + 3 = 6 hours;
5. Determine the average speed of the car along this path:
240: 6 = 40 km / h.
Answer: the car was moving at an average speed of 40 km / h.
