Two trains are moving towards each other at speeds of 60 km / h and 80 km / h. How far will they be from each other 2 hours before the meeting?
1) Let us find the speed at which the given trains approach each other: V1.2 = V1 + V2, where V1 is the speed of the first train (V1 = 60 km / h); V2 is the speed of the second train (V2 = 80 km / h).
V1.2 = V1 + V2 = 60 + 80 = 140 km / h.
2) Determine the distance between the given trains 2 hours before the meeting: S = V1.2 * t, where t is the time before the meeting (t = 2 hours).
S = V1.2 * t = 140 * 2 = 280 km.
Answer: 2 hours before the meeting, the given trains will be at a distance of 280 km from each other.
