Question

Легковая машина по асфальтированной дороге ехала 3 ч со скоростью 76 км\ч, а по степной дороге - 2 ч со скоростью 46 км\ч. Сколько всего километров проехала машина? На сколько километров больше проехала машина по асфальтированной дороге,чем по степной?

Answer 1

76×3=228-это расстояние по асфальту 2×46=92-расстояние по степной дороге 228 -92=136 на столько больше машина проехала по асфальту чем по степи 228+92=320 всего км проехала машина

Answer 2

76×3=228(км)-по асфальтированной дороге.
46×2=92(км)-по степной дороге.
228+92=320(км)-всего проехала машина.
228-92=136(км)

Answer 3

Calculation of Total Distance Traveled

To calculate the total distance traveled by the car, we need to find the distance traveled on the asphalt road and the distance traveled on the steppe road, and then add them together.

The car traveled on the asphalt road for 3 hours at a speed of 76 km/h, and on the steppe road for 2 hours at a speed of 46 km/h.

To find the distance traveled on each road, we can use the formula:

Distance = Speed × Time

For the asphalt road: Distance on asphalt road = 76 km/h × 3 hours

For the steppe road: Distance on steppe road = 46 km/h × 2 hours

To find the total distance traveled, we add the distances on both roads:

Total distance traveled = Distance on asphalt road + Distance on steppe road

Let's calculate the distances:

Distance on asphalt road = 76 km/h × 3 hours = 228 km.

Distance on steppe road = 46 km/h × 2 hours = 92 km.

Total distance traveled = 228 km + 92 km = 320 km.

Therefore, the car traveled a total distance of 320 kilometers.

Difference in Distance Traveled

To find the difference in distance traveled between the asphalt road and the steppe road, we subtract the distance traveled on the steppe road from the distance traveled on the asphalt road.

Difference in distance = Distance on asphalt road - Distance on steppe road

Difference in distance = 228 km - 92 km = 136 km.

Therefore, the car traveled 136 kilometers more on the asphalt road than on the steppe road.
