Final answer:
To find the cost of a 39-minute taxi ride at the same unit price as a 56-minute taxi ride, divide the total cost of the 56-minute ride by the distance of the 56-minute ride. Then, multiply the unit price by the distance of the 39-minute ride to find the cost of the 39-minute ride.
Step-by-step explanation:
To find the cost of a 39-minute taxi ride, we can use the unit price of the 56-minute taxi ride.
First, we need to find the unit price by dividing the total cost of the 56-minute ride ($39.20) by the distance of the 56-minute ride (49 miles).
Then, we can multiply the unit price by the distance of the 39-minute ride (which is proportional to the time) to find the cost of the 39-minute ride.
