Answer: The required number of miles traveled per gallon of gasoline is 31.2 miles.
Step-by-step explanation: Given that Elliot drove 202.8 miles and used 6.5 gallons of gasoline.
We are to find the number of miles that he traveled in one gallon of gasoline.
We will be using the UNITARY method o solve the given problem.
We have
Number of miles traveled in 6.5 gallon of gasoline = 202.8 miles.
Therefore, the number of miles that traveled in 1 gallon of gasoline is given by
Thus, the required number of miles traveled per gallon of gasoline is 31.2 miles.
Answer:
B
Step-by-step explanation:
Note the common difference between consecutive terms of the sequence.
d = 16 - 12 = 20 - 16 = 4
This indicates the sequence is arithmetic with sum to n terms
=
[2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = 12 and d = 4, thus
=
[ (2 × 12) + (41 × 4) ]
= 21( 24 + 164) = 21 × 188 = 3948 → B
