Answer 2

Calculating the Train's Speed

To calculate the speed of the train, we can use the formula: speed = distance / time

Given that the train travels 18 km in 20 minutes, we can calculate its speed using the provided information.

Using the formula: speed = 18 km / 20 minutes

Calculating the Speed

The speed of the train can be calculated as follows: speed = 18 km / 20 minutes

Result

The speed of the train is 54 km/h.

This calculation is based on the given distance and time, and the result is obtained by dividing the distance by the time taken for the train to cover that distance.
