Answer 1

Ответ:

848км

Пошаговое объяснение:

5*87=435км

7*59=413км

435+413=848км

Answer 2

Calculation of the Distance Traveled

To calculate the distance traveled by the bus, we need to determine the distance covered during each leg of the journey and then add them together.

The bus traveled for 5 hours at a speed of 87 km/h on a flat road, and then for 7 hours at a speed of 59 km/h in the mountains.

To find the distance traveled on the flat road, we can multiply the speed by the time: Distance on flat road = Speed on flat road * Time on flat road

Similarly, to find the distance traveled in the mountains, we can multiply the speed by the time: Distance in mountains = Speed in mountains * Time in mountains

Finally, we can add the two distances together to find the total distance traveled: Total distance = Distance on flat road + Distance in mountains

Let's calculate the distances:

Distance on flat road = 87 km/h * 5 hours = 435 km Distance in mountains = 59 km/h * 7 hours = 413 km

Total distance traveled = 435 km + 413 km = 848 km

Therefore, the bus traveled a total distance of 848 kilometers in 12 hours.
