Answer: the trip is 127 1/5 miles
Step-by-step explanation:
The distance that the martinez family drove from home to the ski lodge is 45 4/5 miles. Converting 45 4/5 miles to improper fraction, it becomes 229/5 miles.
Then, they drove an additional 17 4/5 miles to there friends house. Converting 17 4/5 miles to improper fraction, it becomes 89/5 miles
This means that the total distance that they drove while going is
229/5 + 89/5 = 318/5 miles
If the family drove the same route back home, then the distance traveled during there trip is
2 × 318/5 = 636/5 miles
Converting to mixed fraction, it becomes
127 1/5 miles
