Miles rode his mountain bike over some trails in a state park. he biked a total of 5 1/2 miles. how many yards did miles bike? there are 1,760 yards in a mile.

9680 yards. Miles biked a total of 9680 yards.

The key to solve this problem is coverting the Mixed Fraction to Improper Fraction, and make the conversion from miles to yards.

Convert the Mixed Fraction 5 1/2 to an Improper Fraction:

- Multiply the whole number 5 by the denominator

5 x 2 = 10

- Add the result to the numerator

1 + 10 = 11

- Write the Improper Fraction with the same denominator of the Mixed Fraction, and the numerator with the result above

5  1/2 miles >  11/2 miles

To convert miles to yard with mile = 1760 yards:

11/2 * 1760 yards = 19360 yards/2 = 9680 yards

50-60=10
