From two villages along the road, two cyclists left at the same time towards each other, one of whom was traveling at a speed of 16.2 km / h and the other, and the other at a speed of 17 km / h. What is the length of the road between the villages if the cyclists met in 1.5 hours?

1. Length of the road between the villages: S km;
2. The speed of the first cyclist: V1 = 16.2 km;
3. Speed ​​of movement of the second cyclist: V1 = 17 km;
4 Cyclists were riding towards each other. Time: T = 1.5 hours;
The first solution.
5. The total speed (speed of approach) of cyclists: V km / h;
V = V1 + V2 = 16.2 + 17 = 33.2 km / h;
6. Find the distance that the cyclists traveled before the meeting:
S = V * T = 33.2 * 1.5 = 49.8 km;
Second solution.
7. Distance, which the first cyclist will travel to the meeting: S1 km;
S1 = V1 * T = 16.2 * 1.5 = 24.3 km;
8 Distance covered by the second cyclist during the same time: S km;
S = V2 * T = 17 * 1.5 = 25.5 km;
9. Distance between villages:
S = S1 + S2 = 24.3 + 25.5 = 49.8 km.
Answer: the length of the road between the villages is 49.8 km.
