Question

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

Answer 1

3×76=228км по асфальту
2×46=92км по степи
228+92=320км всего проехала
228-92=136км на столько больше

Answer 2

Calculation of Total Distance Traveled

To calculate the total distance traveled by the car, we need to add up the distances traveled on the asphalt road and the steppe road.

The car traveled on the asphalt road for 3 hours at a speed of 76 km/h. Therefore, the distance traveled on the asphalt road is:

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

The car traveled on the steppe road for 2 hours at a speed of 46 km/h. Therefore, the distance traveled on the steppe road is:

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

To find the total distance traveled by the car, we add the distances on the asphalt road and the steppe road:

Total distance traveled = Distance on asphalt road + Distance on steppe road = 228 km + 92 km = 320 km.

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

Difference in Distance Traveled

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

Difference in distance = Distance on asphalt road - Distance on steppe road = 228 km - 92 km = 136 km.

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