To find the train's speed in miles per hour, we need to convert the speed from kilometers per minute to miles per hour.
We know that there are 60 minutes in one hour, and 1.6 kilometers in one mile.
First, we can find the train's speed in kilometers per hour by multiplying the speed (2 km/minute) by the number of minutes in an hour (60 minutes).
2 km/minute * 60 minutes = 120 km/hour
Next, we can convert the speed from kilometers per hour to miles per hour by dividing the speed in kilometers per hour by the number of kilometers in one mile (1.6 kilometers).
120 km/hour ÷ 1.6 km/mile = 75 miles per hour
Therefore, the train's speed in miles per hour is 75 miles per hour, so the answer is 75 miles per hour.
