3. There are about 1.61 kilometers in 1 mile. Let \( x \) represent a distance measured in kilometers and \( y \) represent the same distance measured in miles. Write two equations that relate a distance measured in kilometers and the same distance measured in miles.

To relate distances measured in kilometers and miles, we can use the conversion factor that 1 mile is approximately 1.61 kilometers. 1. The first equation relates kilometers to miles: \[ x = 1.61y \] This equation states that the distance in kilometers \( x \) is equal to 1.61 times the distance in miles \( y \). 2. The second equation can be derived by rearranging the first equation to express miles in terms of kilometers: \[ y = \frac{x}{1.61} \] This equation states that the distance in miles \( y \) is equal to the distance in kilometers \( x \) divided by 1.61. Thus, the two equations that relate a distance measured in kilometers and the same distance measured in miles are: 1. \( x = 1.61y \) 2. \( y = \frac{x}{1.61} \)
