Question

Мимо автомобиля, едущего со скоростью 72км\ч поехал другой автомобиль.Чеоез 10сек расстояние междк ними было 100 метром. Какова скрость второго автомобиля???????? Помогите пожалуйста,завтра кр.работа Ответ должен получиться 108 км\ч непонимаю как

Answer 1

Дано V1=20 м/с   V2- ?

(V2-V1)*t=S
V2=S/t+V1=10+20=30м/с=108км/ч

Answer 2

72 км/ч=20 м/с=v1; s/t=v1-v2; v2=v1+s/t=20+100/10=30 м/с=30*3600/1000=108 км/ч

Answer 3

Calculation of the Second Car's Speed

To calculate the speed of the second car, we can use the formula:

Speed = Distance / Time

Given that the distance between the two cars is 100 meters and the time taken is 10 seconds, we can substitute these values into the formula to find the speed of the second car.

Speed = 100 meters / 10 seconds

Calculating this, we find that the speed of the second car is 10 meters per second.

However, the question asks for the speed in kilometers per hour. To convert meters per second to kilometers per hour, we need to multiply the speed by a conversion factor.

1 meter per second = 3.6 kilometers per hour

So, to convert the speed of the second car from meters per second to kilometers per hour, we multiply the speed by 3.6.

Speed = 10 meters per second * 3.6 = 36 kilometers per hour

Therefore, the speed of the second car is 36 kilometers per hour.

Please note that the calculation assumes constant speed and no acceleration or deceleration during the 10-second interval.
