No one will answer this probably wasting my points XD) Spunky the terrier is chasing a chicken. Spunky runs at a rate of r feet per second while the chicken runs at a rate of v feet per second. The chicken is originally 15 feet from Spunky and he catches up to it in 20 seconds. Which equation represents this information?

a. 20r−15=20v20r-15=20v
b. =20r+20v15=20r+20v
c. 20r=20v−1520r=20v-15
d. 20−15r=20+v
