Помогите решить задачу!Скорый подъезд ехал 3 ч по 82 км в час и 4 ч по 62 км в час. Сколько всего километров проехал подъез за 7 ч?

Answer 1

Problem Analysis

To solve this problem, we need to calculate the total distance traveled by the vehicle during a 7-hour journey. The vehicle traveled at a speed of 82 km/h for 3 hours and at a speed of 62 km/h for 4 hours.

Calculation

To calculate the total distance traveled, we can use the formula:

Distance = Speed × Time

Let's calculate the distance traveled at each speed:

Distance at 82 km/h = 82 km/h × 3 hours

Distance at 62 km/h = 62 km/h × 4 hours

Finally, we can add the two distances together to find the total distance traveled.

Solution

Using the formula mentioned above, we can calculate the distances:

Distance at 82 km/h = 82 km/h × 3 hours = 246 km

Distance at 62 km/h = 62 km/h × 4 hours = 248 km

Total distance traveled = Distance at 82 km/h + Distance at 62 km/h = 246 km + 248 km = 494 km

Therefore, the vehicle traveled a total of 494 kilometers during the 7-hour journey.

Answer

The vehicle traveled a total of 494 kilometers during the 7-hour journey.
