The train traveled 10 km in 10 minutes. At what speed did it go?

The speed of movement of the train will be designated by the conditional variable “Y”.
Based on the data from this example and knowing that one hour contains 60 minutes, we form this equation: Y = 10 / (10/60).
As a result of solving the existing equation, we will have the following value Y = 10 x 60/10 = 60 kilometers per hour.
Answer: the train was moving at a speed of 60 kilometers per hour.
