Select the correct answer.
$1 m=39.37 in$
About how many feet are in 3.6 kilometers?
A. $11,811.00 ft$
B. $141,732.00 ft$
C. 11.81 ft
D. 300.00 ft
Answer (1)
Convert kilometers to meters: 3.6 km = 3600 m .
Convert meters to inches: 3600 m = 141732 in .
Convert inches to feet: 141732 in = 11811 f t .
Therefore, 3.6 kilometers is approximately 11 , 811.00 f t .
Explanation
Understanding the Problem We are given that 1 m = 39.37 in and we need to find out how many feet are in 3.6 kilometers.
Kilometers to Meters First, we convert 3.6 kilometers to meters. We know that 1 km = 1000 m , so we have: 3.6 km = 3.6 km × 1 km 1000 m = 3600 m
Meters to Inches Next, we convert meters to inches using the given conversion factor 1 m = 39.37 in . So, we have: 3600 m = 3600 m × 1 m 39.37 in = 141732 in
Inches to Feet Now, we convert inches to feet. We know that 1 f t = 12 in , so we have: 141732 in = 141732 in × 12 in 1 f t = 11811 f t
Final Answer Therefore, there are approximately 11,811 feet in 3.6 kilometers.
Examples
Imagine you're planning a cross-country trip and want to know the distance in feet, but your GPS only shows kilometers. This problem helps you convert kilometers to feet, allowing you to understand the scale of your journey in a unit you're more familiar with. Knowing how to convert between different units of measurement is useful in many real-world situations, from construction and engineering to travel and everyday problem-solving.
