To find out the number of kilometers covered by the presented train, consider the expression: Sx = V * t, where V is a constant speed (V = 42 1/4 km / h = (168 + 1) / 4 = 169/4 km / h); t – elapsed time (t = 4/13 h).
Let’s perform the calculation: Sx = V * t = 169/4 * 4/13 = 169/13 = 13 km.
Answer: In 4/13 hours the presented train will travel 13 km.
