Question

Из двух сёл одновременно навстречу друг другу вышли два пешехода и встретелись через 1,5 ч расстояние между селами 12,3 км скорость одного пешехода 4,4 км /ч найдите скорость второго пешехода

Answer 1

Ищем скорость сближения пешеходов: 12,3:1,5=8,2 км/ч. Скорость сближения равна сумме скоростей пешеходов. Скорость второго равна 8,2-4,4=
3,8 км/ч.

Answer 2

Calculation of the Second Pedestrian's Speed

To find the speed of the second pedestrian, we can use the formula:

Speed = Distance / Time

Given that the distance between the two villages is 12.3 km and the time it took for the pedestrians to meet is 1.5 hours, we can substitute these values into the formula:

Speed = 12.3 km / 1.5 hours

Calculating this, we find that the speed of the second pedestrian is approximately 8.2 km/h.
