To find the time it will take for the two cars to be 600 km apart, we need to add their distances covered together.
The first car is traveling at a rate of 80 km/h. Since distance = rate * time, we can express the distance covered by the first car as 80t, where t is the time in hours.
Similarly, the second car is traveling at a rate of 70 km/h, and its distance covered can be expressed as 70t.
Since the two cars are traveling in opposite directions, we can add their distances to get the total distance apart: 80t + 70t = 150t.
We need this total distance to be equal to 600 km, so we have the equation 150t = 600.
To solve for t, we divide both sides of the equation by 150: t = 600/150 = 4 hours.
Therefore, it will take them 4 hours to be 600 km apart.
Two cars traveled in opposite directions from the same starting point. The rate of one car is 80 km/h and the other is 70km/h. How long will it take them to be 600 km apart?
