Final answer:
The correct Python expression for converting 5 kilometers into miles, given that 1 mile equals 1.61 km, is 5 / 1.61.
Step-by-step explanation:
The correct Python expression to compute the number of miles in 5 kilometers, where one mile is equivalent to 1.61 kilometers, is 5 / 1.61.
This expression calculates the conversion from kilometers to miles by dividing the distance in kilometers by the conversion factor.
To elaborate on how the expression works, consider that if 1 mile equals 1.61 kilometers, to find out how many miles are in 5 kilometers, you would divide 5 by 1.61.
Therefore, the Python expression A) 5 / 1.61 correctly represents the conversion from 5 kilometers to miles.
