Final answer:
The Johnston family drives 85.91 miles to see family each December. To find the total distance over 5 years, multiply 85.91 by 5, yielding 429.55 miles in total.
Step-by-step explanation:
The question is asking for a simple multiplication calculation to determine the total distance the Johnston family drives over a period of 5 years for their December family visits. Each year, they drive 85.91 miles. To find the total distance driven over 5 years, you would perform the following calculation:
- Multiply the annual distance by the number of years: 85.91 miles/year × 5 years.
So the total distance driven in 5 years would be:
85.91 miles/year × 5 years = 429.55 miles
Therefore, the Johnston family drives a total of 429.55 miles over the course of 5 years.
