During martinez family trip they drove from home to a ski lodge a distance of 45 4/5 miles and then drove an additional 17 4/5 miles to there friends house. If the family drove the same route back home what was the distance traveled during there trip

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

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
