Nattalie picked 135 berries in 15 minutes at this rate how long will it take her to pick 486 berries

forsale [732]

Well, If she takes 15 minutes to pick 135 berries, 30 minutes total would be 270 berries, so if you take another 15 minutes picking berries it would be a total of 405 berries but you still need 81 more. so if she can pick 405 in 45 minutes, it would be around a hour and something.

Hope I helped or at least made you think about it
