Samuel Green recently joined the investment firm of Yoke Pond Associates as an equity analyst. Yoke Pond specializes in international equity investments. This is his first job after college. Sam has just returned from a trip to Germany and the Czech Republic to visit the firm’s offices there. He put 2,100 kilometers on a rental car during the trip and has the following information.
Total spent on gas: €213 and CZK565
Average price of gas at the pump: €1.49/liter
Exchange rates:
One Euro (€) = $1.55
One Czech Koruna (CZK) = $0.064
The car Sam rented had an on-board computer that gave him fuel economy information. Most of his driving was in Germany on the Autobahn at an average speed of 120 km/hr. At this speed, the car indicated his fuel consumption was 8.9 liters/100 km. Some stretches of the Autobahn have no speed limit; Sam enjoyed turning the car loose when this was the case and he could safely do so. He hit a top speed of 182 km/hour and could cruise comfortably at 160 km/hr. At this latter speed, he saw that the current fuel consumption indicator showed 11.2 liters per 100 km.
a. What was his top speed in miles per hour?
b. What was the average pump price of gas in US dollars/gallon?
c. What is the equivalent of 8.9 liters/100 km in the US convention of miles per gallon?
d. He had to fill the gas tank in the rental car before returning it. For the whole trip, what was the average fuel economy in miles per gallon?
