Question

Поезд ехал 5 ч со скоростью a км/ч и 2 ч со скоростью b км/ч. Какое расстояние прошёл поезд за всё это время? ПОМОГИТЕ СРОЧНО!!!!!

Answer 1

Ответ:5×а+2×b

ВОТ ПРАВИЛЬНЫЙ ОТВЕТ

Answer 2

Ответ:

1) S1 = t * v1= 5 ч * а км/час = 5*а км.

2)S2= t * v2= 2 ч * b км/час = 2*b км.

3)S общ = S1 + S2 = 5а+2b км.

Calculation of Distance Traveled by the Train

To calculate the distance traveled by the train, we need to know the speeds of the train during the two different time periods and the durations of those periods.

Let's assume that the train traveled at a speed of a km/h for 5 hours and then at a speed of b km/h for 2 hours.

To calculate the distance traveled during the first period, we use the formula:

Distance = Speed × Time

So, the distance traveled during the first period is a km/h × 5 hours = 5a km.

Similarly, the distance traveled during the second period is b km/h × 2 hours = 2b km.

To find the total distance traveled by the train, we add the distances traveled during the two periods:

Total Distance = Distance of First Period + Distance of Second Period

Total Distance = 5a km + 2b km

Therefore, the train traveled a total distance of 5a + 2b km.

Please provide the values of a and b so that I can calculate the total distance traveled by the train.
