Final answer:
Mrs. Ott and her family will not be able to make it to Atlanta and back with only one charge each way, given the electric car's range of 70 miles and the destination being 92 miles away.
Step-by-step explanation:
The question involves Mrs. Ott and her family planning a trip to the Fox Theatre, which is 92 miles away, in an electric car with a range of approximately 70 miles. Mrs. Ott's past experience indicates that the emergency battery light started blinking 3 miles before reaching home on her previous trip, implying that the car's range with one charge is insufficient for the entire trip of 92 miles. Therefore, to answer the question: Mrs. Ott and her family will not make it to Atlanta and back with only one charge each way. Options B and D are likely accurate; they may have to stop multiple times, and the car's mass will affect its ability to make the trip due to the increased energy needed to move the additional weight.
