Question

велосипедист выехал из города a в город B 4 часа он двигался со скоростью 25 километров в час а потом еще 2 часа со скоростью 20 километров час Найдите расстояние между городами

Answer 1

1) 4 *25 = 100 км - велосипедист проехал за 4 часа
2) 2 * 20 = 40 км - велосипедист проехал за 2 часа
3) 100+40 = 140 км - расстояние между городами А и Б

Answer 2

4*25=100 км
2*20=40 км
100+40=140 км расстояние между городами

Answer 3

Calculation of Distance between City A and City B

To calculate the distance between City A and City B, we need to determine the total distance traveled by the cyclist during the given time period.

According to the information provided, the cyclist traveled from City A to City B for a total of 4 hours. During the first 4 hours, the cyclist traveled at a speed of 25 kilometers per hour. After that, the cyclist continued for an additional 2 hours at a speed of 20 kilometers per hour.

To calculate the distance, we can use the formula:

Distance = Speed × Time

Let's calculate the distance traveled during each segment:

1. Distance traveled during the first 4 hours at a speed of 25 kilometers per hour: - Distance = 25 km/h × 4 h = 100 kilometers

2. Distance traveled during the next 2 hours at a speed of 20 kilometers per hour: - Distance = 20 km/h × 2 h = 40 kilometers

Now, let's calculate the total distance traveled by adding the distances from both segments:

Total Distance = Distance Segment 1 + Distance Segment 2 = 100 kilometers + 40 kilometers = 140 kilometers

Therefore, the distance between City A and City B is 140 kilometers.
