Two motorcyclists drove out of the two cities towards each other. Speed I 70 km / h drove to the meeting-140 km. speed of another 65 km / h. What is the distance between cities?

1. Knowing the speed of the first motorcyclist and the distance he traveled before the meeting, we find by the formula t = S / V (t is time, S is distance, and V is speed), time:
t = 140/70 = 2 (h).
2. Knowing the speed of the second motorcyclist and the time until the meeting, we find the distance traveled by the second motorcyclist using the formula S = V * t:
S = 65 * 2 = 130 (km).
3. Find the distance between cities:
140 + 130 = 270 (km).
Answer: 270 kilometers between cities.
