SUMMARY
The average speed of a train traveling 18 kilometers in 20 minutes is calculated to be 54 kilometers per hour. This is determined using the formula for average speed, v = d/t, where d is distance and t is time. The conversion of 20 minutes to hours is achieved by recognizing that 20 minutes is one-third of an hour, resulting in a straightforward calculation. The discussion emphasizes the importance of using fractions over decimals in certain contexts.
