Final answer:
Camilla's 5K run is approximately 3.1 miles long when converted from kilometers using the conversion factor of 1 mile equals 1.61 kilometers.
Step-by-step explanation:
Camilla decides to register for a 5K run which is a race measuring 5 kilometers in length. To convert this distance to miles, we use the conversion factor that 1 mile is equal to 1.61 kilometers. Therefore, to find the equivalent distance in miles, we divide the number of kilometers by the number of kilometers per mile:
5 km ÷ 1.61 km/mile = 3.105 miles (approximately).
Thus, Camilla is going to run approximately 3.1 miles in the 5K race.
