Question

Навстречу друг другу выехали два автомобиля.Один ехал со скоростью 60 км/ч,а другой-65 км/ч.На сколько километров они сблизятся за 1 ч движения?А за 2 ч?

Answer 1

60*1=60   65*1=65   65+60=125 км сблизятся за 1 час .60*2=120   65*2=130    120+130=250км сблизятся за 2 часа

Answer 2

Problem Analysis

Two cars are moving towards each other, one at a speed of 60 km/h and the other at a speed of 65 km/h. We need to calculate how many kilometers they will approach each other in 1 hour and 2 hours.

Solution

To find out how many kilometers the cars will approach each other, we need to calculate the total distance covered by both cars in the given time.

Let's calculate the distance covered by the first car in 1 hour: - Speed of the first car = 60 km/h - Time = 1 hour - Distance covered by the first car in 1 hour = Speed * Time = 60 km/h * 1 hour = 60 km

Similarly, let's calculate the distance covered by the second car in 1 hour: - Speed of the second car = 65 km/h - Time = 1 hour - Distance covered by the second car in 1 hour = Speed * Time = 65 km/h * 1 hour = 65 km

To find out the total distance covered by both cars in 1 hour, we can add the distances covered by each car: - Total distance covered by both cars in 1 hour = Distance covered by the first car + Distance covered by the second car = 60 km + 65 km = 125 km

Now, let's calculate the distance covered by the first car in 2 hours: - Speed of the first car = 60 km/h - Time = 2 hours - Distance covered by the first car in 2 hours = Speed * Time = 60 km/h * 2 hours = 120 km

Similarly, let's calculate the distance covered by the second car in 2 hours: - Speed of the second car = 65 km/h - Time = 2 hours - Distance covered by the second car in 2 hours = Speed * Time = 65 km/h * 2 hours = 130 km

To find out the total distance covered by both cars in 2 hours, we can add the distances covered by each car: - Total distance covered by both cars in 2 hours = Distance covered by the first car + Distance covered by the second car = 120 km + 130 km = 250 km

Therefore, the two cars will approach each other by 125 kilometers in 1 hour and 250 kilometers in 2 hours.

Answer

The two cars will approach each other by 125 kilometers in 1 hour and 250 kilometers in 2 hours.
