Question

A train travels at 3km per minute. What is the train's speed in miles per hour? Round to the nearest tenth

Answer 1

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.
