Answer 2

Calculation of Pedestrian Speed

To calculate the speed of the pedestrians, we need to determine the time it took for each pedestrian to cover their respective distances.

Let's assume the speed of the pedestrians is denoted by v (in km/h), the distance covered by the first pedestrian is d1 (4 km), and the distance covered by the second pedestrian is d2 (8 km). We are also given that the first pedestrian took 40 minutes less time than the second pedestrian.

We can use the formula speed = distance / time to calculate the speed of the pedestrians.

Let's calculate the time taken by each pedestrian:

- The first pedestrian covered a distance of 4 km and took 40 minutes less time than the second pedestrian. Let's denote the time taken by the first pedestrian as t1. - The second pedestrian covered a distance of 8 km. Let's denote the time taken by the second pedestrian as t2.

From the given information, we can write the following equations:

d1 = v * t1 (Equation 1) d2 = v * t2 (Equation 2) **t1 = t2
