Solving the Problem Using Equations

To solve the problem of the distance between two runners over time, we can use the equation of motion. The equation we will use is:

Distance = Initial Distance + (Initial Velocity × Time) + (0.5 × Acceleration × Time²)

In this case, the initial distance between the runners is 0 meters, as they start at the same point. The initial velocities of the first and second runners are 4 m/s and 2 m/s, respectively. The acceleration is 0 since we are assuming constant velocity.

Let's substitute the given values into the equation and solve for time:

Distance = 0 + (4 × Time) + (0.5 × 0 × Time²)

Simplifying the equation, we get:

Distance = 4 × Time

Now, we can solve for time when the distance between the runners is 80 meters:

80 = 4 × Time

Dividing both sides of the equation by 4, we find:

Time = 20 seconds

Therefore, it will take 20 seconds for the distance between the runners to be 80 meters.

I hope this helps! Let me know if you have any further questions.
