Answer:
The car's average 18 number of miles per gallon
Step-by-step explanation:
The car has different efficiencies depending if its used on highway or city streets.
The efficiency on a highway is:
The efficiency for city driving is:
We now that the car uses twice as many gallons for city driving as for highway driving. This means that, for every gallon consumed, 2/3 are for city driving and 1/3 are for highway driving.
Then, we can calculate how many miles makes the car on average as:
Answer:
68 inches
Step-by-step explanation:
P = 2 (L + W)
P = 2(4x+5 + 4x+5)
P = 2(8x + 10)
P = 16x + 20
If x= 3
P = 16(3) + 20
P = 48 + 20
P = 68 inches
