You know 1mi= 1,760 yd. How many yd is 10 mi ?
There are 1760 yards in one mile.
To get to the ten miles, you multiplied the one mile by ten. So, you now multiply the 1760 yards by 10 to get your answer.
1760 x 10 = 17,600
Good luck!
17,600 because when you have ten multiplied to any # you can just add and extra zero to the #
