Question

A car has two gallons of fuel left in it. Depending on the terrain and the elevation it can cover different distances across different routes. This data is represented in the given radar chart. If each rung in the chart represents a distance of 20 miles, calculate the average fuel efficiency of the car in miles per gallon.

• A. 26 mpg
• B. 24 mpg
• C. 20 mpg
• D. 22 mpg

Answer 1

The correct option is A 26 mpg

Upon writing down the distance that can be covered across each route, we get:

$Downhillhighway⟹20miles\times 4=80miles$

$Downhillunpaved⟹20miles\times 3=60miles$

$Uphillunpaved⟹20miles\times 1=20miles$

$Uphillpaved⟹20miles\times 2=40miles$

$Uphillhighway⟹20miles\times 3=60miles$

Calculating the average distance that could be covered, we get:

$Average=\frac{80+60+20+40+60}{5}=52miles$

$Totalamountoffuelinthetank=2gal$

$⟹Fuelefficiency\left(mpg\right)=\frac{52}{2}=26mpg$
