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. Do not label.(1 point) Responses 180 miles per hour 180 miles per hour 112.5 miles per hour 112.5 miles per hour 4.8 miles per hour 4.8 miles per hour .05 miles per hour
To convert the train's speed from kilometers per minute to miles per hour, we can use the following conversion factors:
1 kilometer = 0.621371 miles
1 minute = 1/60 hour
First, we need to find the train's speed in kilometers per hour:
3 km/minute * 60 minutes/hour = 180 km/hour
Next, we can convert kilometers to miles:
180 km/hour * 0.621371 miles/kilometer = 111.85 miles/hour
Rounding to the nearest tenth, the train's speed in miles per hour is approximately 111.9 miles per hour.
What is the answer
The answer is 111.9 miles per hour.
To convert the train's speed from kilometers per minute to miles per hour, you need to follow these steps:
1. Convert the train's speed from kilometers per minute to kilometers per hour. Since there are 60 minutes in 1 hour, multiply the train's speed by 60 to get the speed in kilometers per hour:
Speed in kilometers per hour = 3 km/minute × 60 minutes/hour = 180 km/h
2. Convert the speed from kilometers per hour to miles per hour. Since there are about 1.6 kilometers in 1 mile, divide the speed in kilometers per hour by 1.6 to get the speed in miles per hour:
Speed in miles per hour = 180 km/h ÷ 1.6 = 112.5 mph
Therefore, the train's speed in miles per hour is approximately 112.5 mph.
