Charles loves to ride his bike. he can cycle 22 miles in 120 minutes. How many miles can he travel in 180 minutes?
the answer is 33. how do you get from 12 to 180. you add 60, 60 is half of 120. So if you want to find the miles, you must cut 22 in half, (You get 11) and add it with 22 which equals 33. Hope this helps :)
