Question

While in Europe, if you drive 119 km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per liter and your car's gas mileage is 30.0 mi/gal ? Assume that 1euro=1.26dollars.

Answer 1

We have to convert:
1 km = 0.62173 mi
1 lit = 0.264172 gallons
119 * 0.62173 = 73.943 mi per day
73.943 : 30 = 2.4648 gal per day
2.4648 : 0.264172 * 1.10 = 10.26 Euros per day
In one week :
10.26 * 7 = 71.28 Euros
71.28 * 1.26 = $90.50
Answer:   
You would spend $90.50 in one week.
