Question

Петя и Вова вышли из своих домов навстречу друг другу и встретились через 7 минут.Какое расстояние между домами Пети и Вовы,если Петя шел со скоростью 30 м/мин,а Вова со скоростью 40 м/мин?

Answer 1

1) 30 х 7 = 210 м - Петя прошел до точки встречи

2) 40 х 7 = 280 м - Вова прошел до точки встречи

3) 210 + 280=490 м - расстояние между домами

 

Answer 2

Calculation of the Distance

To calculate the distance between the houses of Petya and Vova, we can use the formula: distance = speed * time.

Given that Petya walked at a speed of 30 m/min and Vova walked at a speed of 40 m/min, and they met after 7 minutes, we can calculate the distance between their houses.

The distance traveled by Petya can be calculated as follows: distance_Petya = speed_Petya * time = 30 m/min * 7 min = 210 meters. Similarly, the distance traveled by Vova can be calculated as follows: distance_Vova = speed_Vova * time = 40 m/min * 7 min = 280 meters. Therefore, the distance between the houses of Petya and Vova is the sum of the distances traveled by each of them: distance_total = distance_Petya + distance_Vova = 210 meters + 280 meters = 490 meters.

So, the distance between the houses of Petya and Vova is 490 meters.
