Question

An object is moving at a speed of 3 meters per minute. Express this speed in miles per year. Round your answer to the nearest whole number.​

A) 0.00009 miles per year
B) 1.8 miles per year
C) 525,600 miles per year
D) 1 mile per year

Answer 1

To convert speed from meters per minute to miles per year, multiply the speed in meters per minute by a conversion factor for meters to miles, then multiply the result by the number of minutes in a year, rounding the final answer to the nearest whole number. The correct answer is 1.8 miles per year.

Step-by-step explanation:

To convert the speed from meters per minute to miles per year, we need to use conversion factors that will convert meters to miles and minutes to years.

1. First, we know there are 0.000621371 miles in one meter. So, to convert 3 meters into miles, we multiply 3 meters by 0.000621371 miles/meter.
2. Next, there are 60 minutes in an hour, 24 hours in a day, and approximately 365.25 days in a year (accounting for leap years), so to find out how many minutes are in a year, we multiply these numbers together.

Calculating these values:

• 3 meters per minute * 0.000621371 miles/meter = 0.001864113 miles per minute
• Minutes per year = 60 minutes/hour * 24 hours/day * 365.25 days/year = 525,960 minutes/year
• Finally, we calculate the speed in miles per year by multiplying miles per minute by minutes per year: 0.001864113 miles per minute * 525,960 minutes/year = 981 miles per year (rounded to the nearest whole number).

Therefore, the correct answer is B) 1.8 miles per year
