Two trains left the two cities at the same time to meet each other and met in 7 hours. the first train was traveling at a speed of 48 km / h. Which train speed is greater and how much. if the distance by cities is 700 km
Let’s find the speed of the convergence of trains:
700: 7 = 100 km per hour.
Since the trains were moving towards each other, the speed of convergence is equal to the sum of their speeds, then the speed of one of them is equal to the difference between the speed of convergence and the speed of the other:
100-48 = 52 km / h.
The speed of the second train is higher by:
52-48 = 4 km / h.
