His trip and used 175 L of gasoline, filling his tank at an average cost of 1.23 euros per liter. Who paid more per kilometer driven cor their trip?

Answer 1

Answer:

• Britta paid more per kilometer driven

Explanation:

1) Britta:

• Distance traveled: 1,250 Km

• Gasoline used: 209 liter

• Gasoline price: 1.23 euros / liter

Cost per km = total cost of gasoline / distance traveled

Cost per km = gasoline used × gasoline price / distance traveled

Cost per km = 209 liter × 1.14 (euro / liter) / 1,250 km =  0.19 euro / km

2) Pierce:

• Distance traveled: 1,405 km

• Gasoline used: 175 liter

• Gasoline price = 1.23 euros / liter

Cost per km = 175 liter × 1.23 (euro / liter) / 1,405 km =  0.15 euro / km

3) Comparison:

• 0.19 > 0.15 ⇒ Britta paid more per kilometer driven
