A train travels at 3km per minute. What is the train's speed in miles per hour? Round to the nearest tenth
To convert from kilometers per minute to miles per hour, we need to make two conversions: kilometers to miles and minutes to hours.
1 kilometer is equal to 0.621371 miles.
1 hour is equal to 60 minutes.
So, the train's speed in miles per hour is:
3 km/minute * 0.621371 miles per kilometer * 60 minutes per hour = 111.84786 miles per hour
Rounded to the nearest tenth, the train's speed is 111.8 miles per hour.
