| **2 cyclists are riding towards each other. Distance 42000 m, speed of the first 8m / s, they met in 50 minutes, find the speed of the second. Which formula should you use?**

These tasks: oncoming traffic; S (initial distance between cyclists) = 42,000 m; V1 (speed of the first cyclist) = 8 m / s; t (time elapsed before the meeting) = 50 minutes (in SI t = 3000 s).

To determine the required speed of the second cyclist, we use the formula for calculating the speed of oncoming traffic: V1.2 = V1 + V2 = S / t, whence V = S / t – V1.

Let’s make a calculation: V = 42000/3000 – 8 = 14 – 8 = 6 m / s.

Answer: The desired speed of the second cyclist is 6 m / s.
