Answer:
300 yards.
Step-by-step explanation:
( we will use "x" for the total number of yards that will be walked in total, and "*" for the multiplication symbol. )
30% of x = 90
30 * x / 100 = 90
To solve for x, we have to multiply both sides by 100 and then divide both sides by 30 to get x=300.
Therefore, the answer to 90 yards is 30 percent of 300 yards.
