Question

Поезд ехал 4ч со скоростью 65км/ч а в последний пятый час увеличил скорость на 10км/ч. Найди расстояние , которое он проехал.

Answer 1

1)с какой скоростью поезд ехал последний час?

65+10=75 км/час 

2)сколько км поезд проехал за 4 часа?

4*65= 260 км

3)расстояние которое проехал поезд

260+65= 325 км

Answer 2

Calculation of Distance Traveled by the Train

To calculate the distance traveled by the train, we need to consider the different speeds and durations of travel.

Given information: - The train traveled for 4 hours at a speed of 65 km/h. - In the last hour, the train increased its speed by 10 km/h.

To find the distance traveled, we can calculate the distance covered in the first 4 hours and add the distance covered in the last hour.

Distance covered in the first 4 hours: - Speed: 65 km/h - Time: 4 hours

Using the formula distance = speed × time, we can calculate the distance covered in the first 4 hours: Distance = 65 km/h × 4 hours = 260 km

Distance covered in the last hour: - Speed: 65 km/h + 10 km/h = 75 km/h - Time: 1 hour

Using the same formula, we can calculate the distance covered in the last hour: Distance = 75 km/h × 1 hour = 75 km

Total distance traveled: To find the total distance traveled, we add the distance covered in the first 4 hours to the distance covered in the last hour: Total distance = Distance in the first 4 hours + Distance in the last hour = 260 km + 75 km = 335 km

Therefore, the train traveled a distance of 335 km.
