Question

Car A is rated at 32 ​mi/gal (miles per​ gallon) for city driving and 29 ​mi/gal for highway driving. Car B is rated at 27 ​mi/gal city and 34 ​mi/gal highway. How many gallons of gas would each vehicle consume for the following amounts of​ driving?
​(a) 300 mi of city driving plus 100 mi of highway driving
​(b) 100 mi of city driving plus 300 mi of highway driving

Answer 1

The gallons of gas that each vehicle would consume for the different amounts of driving are as follows:

a) For 300 mi of city driving plus 100 mi of highway driving, car A will consume 12.825 gallons of gas, while car B will consume 14.05 gallons of gas.

b) For 100 mi of city driving plus 300 mi of highway driving, car A will consume 13.475 gallons of gas, while car B will consume 12.52 gallons of gas.

Data and Calculations:

Rating (miles per gallon)

                                           City Driving     Highway Driving

Car A                                     32 mi/gal            29 mi/gal

Car B                                     27 mi/gal            34 mi/gal

Miles of Driving

                   City Driving     Highway Driving

a)                       300 mi              100 mi

b)                       100 mi              300 mi

Car A's Consumption of Gas:

                   City Driving               Highway Driving              Total

a)              9.375 gal.(300/32)         3.45 gal. (100/29)        12.825 gal.

b)              3.125 gal.(100/32)         10.35 gal    (300/29)     13.475 gal.

Car B's Consumption of Gas:

                   City Driving               Highway Driving             Total

a)                11.11 gal. (300/27)         2.94 gal. (100/34)         14.05 gal.

b)              3.70 gal. (100/27)          8.82 gal. (300/34)        12.52 gal.

Thus, different driving ratings (miles per gallon) show the differences in gas consumption by vehicles in city driving and highway driving.
