A train covers a distance of 300 kilometers in 5 hours. If the same train takes 6 hours to cover the same distance, what is the change in its speed?
10 km/h decrease
Speed \(=\) Distance \(\div\) Time.
Initial speed \(= \frac{300}{5} = 60\) km/h.
New speed \(= \frac{300}{6} = 50\) km/h.
Change in speed \(= 60 - 50 = 10\) km/h, and since the new speed is lower, it is a decrease.
Hence, the change is a decrease of 10 km/h.
