a train travels 3 km per minute. What is the train's speed in miles per hour there are about 1.6 kilometers in 1 mile. 60 minutes in 1 hour. Round to the nearest tenth show your work in number form
A 180
B 112.5
C 4.8
D 0.5
To find the train's speed in miles per hour, we need to convert kilometers per minute to miles per hour.
First, we know that there are 1.6 kilometers in 1 mile. So, the train's speed in kilometers per hour is:
3 km/minute * 60 minutes/hour = 180 km/hour
Now, we need to convert kilometers to miles. We know that 1 mile is equal to 1.6 kilometers. So, the train's speed in miles per hour is:
180 km/hour / 1.6 km/mile = 112.5 miles/hour
Therefore, the correct answer is B) 112.5.
