Final answer:
To convert 320 kilometers to miles, multiply 320 by the reciprocal of the conversion factor, 1/1.61, since 1 mile equals 1.61 kilometers. The answer is approximately 198.76 miles.
Step-by-step explanation:
The student's question is about converting a distance from kilometers to miles. The provided conversion factor is that 1 mile is equivalent to 1.61 kilometers. To convert 320 kilometers to miles, you would use the following formula:
Miles = Kilometers × Conversion Factor
Therefore, to find out how many miles are in 320 kilometers, calculate:
Miles = 320km × (1 mile/1.61km)
Now, you can divide 320 by 1.61 to get the answer in miles. After performing the calculation, the distance in miles is approximately:
198.76 miles
Note that we used the reciprocal of the unit conversion given in the question (5/8 km) because it was not relevant to this conversion task. The common conversion factor to use is 1 mile = 1.61 km.
