Answer 1

To find the train's speed in miles per hour, we need to convert the speed from km/minute to miles/hour.

1 km = 0.62 miles (approximately)

So, the train's speed in miles per minute is:
3 km/minute * 0.62 miles/km = 1.86 miles/minute

To convert this to miles per hour, we need to multiply by 60 (because there are 60 minutes in an hour):
1.86 miles/minute * 60 minutes/hour = 111.6 miles/hour

Rounded to the nearest whole number, the train's speed is approximately 112 miles per hour.
