Final answer:
Jackie should pay $27.95 USD to the Uber driver for her 30 kilometers trip in Europe.
Step-by-step explanation:
To calculate how much Jackie should pay the Uber driver for her 30 kilometers trip, we need to convert kilometers to miles, since the cost is given in USD per mile. We know that 1 mile is approximately 1.61 kilometers. So, we can divide 30 kilometers by 1.61 to get the equivalent number of miles. Using this conversion, Jackie traveled approximately 18.63 miles. Now, we can multiply the number of miles by the cost per mile, which is $1.50. Multiplying 18.63 miles by $1.50 gives us a total cost of $27.95 USD.
