Question

С городов А и Б одновременно навстречу друг другу выехали два поезда со скоростью 51 и 59 км в час Найди растояние между городами А и Б если поезда встретились через 4 часа

Answer 1

51+59=110км/ч- общая скорость поездов 
110*4=440 км- расстояние преехавшее за 4 часа

Answer 2

51+59=110км в ч

110*4=440 км

Answer 3

Calculation of Distance between Cities A and B

To find the distance between cities A and B, we can use the formula:

Distance = Speed x Time

Given that two trains, one from city A and the other from city B, are traveling towards each other, we can calculate the distance between the cities using the speeds and the time it takes for them to meet.

Let's calculate the distance step by step:

1. The first train is traveling at a speed of 51 km/h. 2. The second train is traveling at a speed of 59 km/h. 3. The trains meet after 4 hours.

Using the formula mentioned above, we can calculate the distance between the cities:

Distance = (Speed of Train A + Speed of Train B) x Time

Distance = (51 km/h + 59 km/h) x 4 hours

Distance = 110 km/h x 4 hours

Distance = 440 km

Therefore, the distance between cities A and B is 440 kilometers.

Please note that the above calculation assumes a constant speed for both trains throughout the journey.
