Question

Пж помогите:автобус и машина одновреммено выехали из двух городов расстояние 600км скоростьавтобуса 50 км/ч а машины 60км ч какое расстояние между ними через 2 ч после выхода?через сколько времени после выхода они встретились?

Answer 1

Дано:
А-V=50км/ч
М-V=60км/ч
S=600
Решение:
1)50+60=110(км/ч)-общ V
2)110*2=220(км)-S за 2 ч
3)600-220=380(км)-S между А и М
Ответ:S между А и М равно 380 км
Р.S. На второй вопрос времени нету:(

Answer 2

Calculation of Distance and Time

To calculate the distance between the bus and the car after 2 hours and the time it takes for them to meet, we can use the formula:

Distance = Speed x Time

Given that the bus is traveling at a speed of 50 km/h and the car is traveling at a speed of 60 km/h, we can calculate the distance between them after 2 hours:

Distance = (Bus Speed x Time) + (Car Speed x Time)

Substituting the values:

Distance = (50 km/h x 2 h) + (60 km/h x 2 h)

Simplifying the equation:

Distance = 100 km + 120 km

Distance = 220 km

Therefore, the distance between the bus and the car after 2 hours is 220 km.

To calculate the time it takes for them to meet, we can use the formula:

Time = Distance / Relative Speed

The relative speed is the difference in speed between the bus and the car:

Relative Speed = Car Speed - Bus Speed

Substituting the values:

Relative Speed = 60 km/h - 50 km/h

Relative Speed = 10 km/h

Now we can calculate the time it takes for them to meet:

Time = Distance / Relative Speed

Substituting the values:

Time = 220 km / 10 km/h

Simplifying the equation:

Time = 22 hours

Therefore, the bus and the car will meet after 22 hours.

Please note that the above calculations assume that the bus and the car are traveling in the same direction. If they are traveling in opposite directions, the calculations would be different.
