Question

Поезд должен пройти 1060 км за 14 ч. Первые 420 км он шел со скоростью 70 км/ч. С какой скоростью он должен идти оставшийся путь, чтобы прибыть в пункт назначения вовремя?

Answer 1

420/70=6
14-6=8
1060-420=640
640/8=80

Answer 2

1) 420:70=6 (час) потратил позд на первом участке.
2)14-6=8(час) осталось идтм.
3) 1060-420=640(км) осталось пройти.
4)640:8=80(км в час) новая скорость.
 Ответ 80

Answer 3

Problem Analysis

We are given that a train needs to travel a total distance of 1060 km in 14 hours. The train has already traveled the first 420 km at a speed of 70 km/h. We need to determine the speed at which the train should travel the remaining distance in order to arrive at its destination on time.

Solution

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

Speed = Distance / Time

Let's calculate the remaining distance and time:

Remaining distance = Total distance - Distance already traveled Remaining distance = 1060 km - 420 km = 640 km

Remaining time = Total time - Time already taken Remaining time = 14 hours - 14 hours = 0 hours

Since the remaining time is 0 hours, it means that the train has already used up all the allotted time and will not be able to reach its destination on time. Therefore, there is no specific speed at which the train should travel the remaining distance.

Answer

The train will not be able to reach its destination on time as the remaining time is 0 hours. Therefore, there is no specific speed at which the train should travel the remaining distance.
