Kameron walks 3 miles in 18 minutes.how many can kameron walk in 120 minutes
Pani-rosa [81]

Answer:

20

Step-by-step explanation:

start by dividing 18 from 120(to find the amount of 18's in 120)

120 / 18 = 6.<u>6</u>

meaning there are 6.<u>6</u> sets of 18 in 120

multiply 3 by 6.<u>6</u>(since there's 3 miles for every 18 minutes)

3 x 6.<u>6</u> = 20
