Two friends start running in an opposite direction from the same point. One friend runs 2km/h faster than the other. After one hour, they are 10 km apart. What is the speed of both friends:

🧠 Explanation:

Two friends running in opposite directions, one 2 km/h faster, are 10 km apart after one hour. Their speeds are 4 km/h and 6 km/h. If the slower friend’s speed is x, the faster is x+2. Their combined speed (x + x + 2 = 2x + 2) covers 10 km in one hour, so 2x + 2 = 10, giving x = 4. Thus, speeds are 4 km/h and 6 km/h. This problem tests algebraic reasoning, relevant in physics or logistics for calculating relative motion.
