Question

Поезд прошёл 352 км. 3 часа он шёл со скоростью 48 км/час . Остальную часть пути прошёл за 4 час. С какой скоростью шёл поезд остальной путь.

Answer 1

1) 3*48=144 (км)- он прошел за 3 часа

2) 352-144=208 (км) - осталось

3) 208/4=52 (км/ч)

Ответ: 52 км/ч

Answer 2

3*48=144 км-прошел поезд за 3 ч

352-144=208км-осталось пройти

208/4=52 км/ч двигался с этой скоростью поезд

Answer 3

Problem Analysis

We are given that a train traveled a total distance of 352 km. The train traveled at a speed of 48 km/h for 3 hours and the remaining distance was covered in 4 hours. We need to find the speed at which the train traveled the remaining distance.

Solution

To find the speed at which the train traveled the remaining distance, we can use the formula:

Speed = Distance / Time

Let's calculate the speed at which the train traveled the remaining distance.

Calculation

The train traveled a distance of 352 km in total. It traveled at a speed of 48 km/h for 3 hours. Therefore, the distance covered in the first 3 hours is:

Distance = Speed x Time = 48 km/h x 3 hours = 144 km

The remaining distance is:

Remaining Distance = Total Distance - Distance Covered = 352 km - 144 km = 208 km

The remaining distance was covered in 4 hours. Therefore, the speed at which the train traveled the remaining distance is:

Speed = Remaining Distance / Time = 208 km / 4 hours = 52 km/h

Answer

The train traveled the remaining distance at a speed of 52 km/h.
