Question

Из города А и Б расстояние между которыми 1500 км вышли Одновременно навстречу два поезда поезд из города а шёл со скоростью 7 км ч С какой скоростью шел поезд из города б если они встретились в 700 км Из города А

Answer 1

700/7=100(часов шли поезда)
1500/100=15(общ. ск. км. в час)
15-7=8
Ответ:поезд из города Б шел со скоростью 8 км в час

Answer 2

Calculating the Speed of the Train from City B

To calculate the speed of the train from city B, we can use the formula:

Speed = Distance / Time

Given: - Distance between city A and city B = 1500 km - Speed of the train from city A = 7 km/h - They met at a distance of 700 km from city A

We can calculate the time it took for the trains to meet using the formula: Time = Distance / (Speed A + Speed B)

Substituting the given values: 700 / (7 + Speed B) = Time

We can then solve for the speed of the train from city B.

Calculation

Using the given information, we can calculate the speed of the train from city B.

700 / (7 + Speed B) = Time

700 / (7 + Speed B) = 700 / (7 + Speed B)

700(7 + Speed B) = 700(7 + Speed B)

4900 + 700Speed B = 4900 + 700Speed B

700Speed B = 700Speed B

This equation shows that the speed of the train from city B can be any value, as both sides of the equation are equal. Therefore, the speed of the train from city B cannot be determined with the given information.
