A train travels 2 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. Do not label.

Question

150 miles per hour
225 miles per hour
75 miles per hour
3.2 miles per hour

Answer 1

To find the train's speed in miles per hour, we need to convert kilometers to miles and minutes to hours.

First, we can find the train's speed in kilometers per hour:
2 km/min * 60 min/hr = 120 km/hr

Next, we can convert kilometers to miles:
120 km/hr / 1.6 km/mi ≈ 75 miles per hour

Therefore, the train's speed is approximately 75 miles per hour. So the correct answer is 75 miles per hour.
