Question

Из москвы в санктпетербург выехали одновременно две машины одна соскоростью 90 км/ч другая со скоростью 78 км/ч какое расстояние будет между ними через час?

Answer 1

90 * 1 = 90 км проедет 1 машина за 1 час
78 * 1 = 78 км проедет 2 машина за 1 час
90 - 78 = 12 км будет между ними через час

Answer 2

Calculating the Distance Between the Two Cities

To calculate the distance between the two cars after one hour, we can use the formula:

Distance = Speed × Time

Let's calculate the distance for each car: - Car 1: Speed = 90 km/h, Time = 1 hour - Car 2: Speed = 78 km/h, Time = 1 hour

Distance for Car 1: 90 km/h × 1 hour = 90 km

Distance for Car 2: 78 km/h × 1 hour = 78 km

So, after one hour, the distance between the two cars will be the difference in the distances they have traveled, which is: 90 km - 78 km = 12 km.

Therefore, after one hour, there will be a distance of 12 kilometers between the two cars.

I hope this helps! If you have any other questions, feel free to ask.
