To find the train's speed in miles per hour, we can use the given conversion factor that there are approximately 1.6 kilometers in 1 mile.
First, we need to convert the 3 km per minute into km per hour. Since there are 60 minutes in 1 hour, we multiply 3 km by 60 to get the distance in kilometers per hour: 3 km/min * 60 min/hour = 180 km/hour.
Next, we convert the km per hour into miles per hour using the conversion factor of 1.6 km in 1 mile. Divide 180 km/hour by 1.6 km/mile to get the speed in miles per hour: 180 km/hour / 1.6 km/mile = 112.5 miles/hour.
Therefore, the train's speed in miles per hour is approximately 112.5 miles/hour.
