Problem Analysis

Two cars start simultaneously from the same point in the same direction. One car is traveling at a speed of 85 kilometers per hour, while the other car is traveling at a speed of 60 kilometers per hour. We need to determine how many hours it will take for the distance between the two cars to be 100 kilometers.

Solution

To solve this problem, we can use the formula: distance = speed × time.

Let's assume that the time it takes for the distance between the two cars to be 100 kilometers is t hours.

The distance traveled by the first car in t hours is given by: distance1 = speed1 × t.

The distance traveled by the second car in t hours is given by: distance2 = speed2 × t.

According to the problem, the difference between the distances traveled by the two cars is 100 kilometers: distance1 - distance2 = 100.

Substituting the values, we get: (speed1 × t) - (speed2 × t) = 100.

Simplifying the equation, we have: (85 × t) - (60 × t) = 100.

Solving for t, we get: 25 × t = 100.

Dividing both sides of the equation by 25, we find: t = 4.

Therefore, it will take 4 hours for the distance between the two cars to be 100 kilometers.

Answer

It will take 4 hours for the distance between the two cars to be 100 kilometers.
