Question

Из двух города выехали две машины одновременно навстречу одна другой и встретились через 4 ч. какое расстояние между городами если скорости машин 75км в час и 82км в час

Answer 1

75*4+82*4=300+328=628 км 

Answer 2

1) 75+82=157(км/ч) - скорость сближения.
2) 157 * 4 = 628 (км0
Ответ: 628 км - расстояние между городами.

Answer 3

Calculating the Distance Between Two Cities

To calculate the distance between two cities when two cars travel towards each other at different speeds, we can use the formula:

Distance = Speed * Time

Given: - Car 1 speed = 75 km/h - Car 2 speed = 82 km/h - Time taken to meet = 4 hours

Calculating the Distance Traveled by Each Car

Using the formula, we can calculate the distance traveled by each car before they meet:

- Distance traveled by Car 1 = 75 km/h * 4 h = 300 km - Distance traveled by Car 2 = 82 km/h * 4 h = 328 km

Calculating the Total Distance Between the Cities

The total distance between the two cities is the sum of the distances traveled by each car before they meet:

Total distance = Distance traveled by Car 1 + Distance traveled by Car 2

Total distance = 300 km + 328 km = 628 km

Therefore, the distance between the two cities is 628 kilometers.
