Answer 1

1) 80÷2=40км
2) 70÷2=35км
3) 300÷(40+35)=4ч
4) (80+70)×4=600км
5) 600-300=300км
Ответ:300км будет между ними

Answer 2

Given Information:

- The speed of the first car is 70 km/h. - The speed of the second car is 80 km/h. - The distance between the two cities is 300 km.

Time taken for the cars to meet:

To find out when the two cars will meet, we can use the formula: time = distance / relative speed.

The relative speed of the two cars is the sum of their speeds, which is 70 km/h + 80 km/h = 150 km/h.

Plugging in the values, we get: time = 300 km / 150 km/h = 2 hours.

Therefore, the two cars will meet after 2 hours.

Distance between the cars after 2 hours:

To find out the distance between the two cars after 2 hours, we can use the formula: distance = speed * time.

The speed of the first car is 70 km/h, and the time is 2 hours. Plugging in the values, we get: distance = 70 km/h * 2 hours = 140 km.

The speed of the second car is 80 km/h, and the time is 2 hours. Plugging in the values, we get: distance = 80 km/h * 2 hours = 160 km.

Therefore, the distance between the two cars after 2 hours will be 140 km and 160 km, respectively.
