[Question]My cat's empty bowl weighs 420 grams. If I give my cat 60 grams per day and I always fill her bowl every 3 days, how much does her bowl weigh if after I ended up refilling her empty bowl she only ate 14 grams?
[Answer]If I give my cat 60 grams per day and I fill it to last 3 days, then I put a total of 60 * 3 = 180 grams into her bowl. If the empty bowl weighs 420 grams and I put 180 grams the total weight is = 420 + 180 = 600 grams. If my cat only ate 14 grams then the bowl right now weighs 600 - 14 = 586 grams. The answer is 586.
Q: The sum of the ages of Jeremy, Sebastian and Sophia in three years is 150. Currently, Sebastian is 4 years older than Jeremy. If Jeremy's age is 40, calculate Sophia's age three years from now?
A: The age of Jeremy three years from now will be 40 + 3 = 43 years. Since Sebastian age is four years more than Jeremy's, Sebastian is currently 40 + 4 = 44 years. In three years, Sebastian will be 44 + 3 = 47 years old. The total age of Jeremy and Sebastian in three years will be 47 + 43 = 90. If the total age of Jeremy, Sebastian and Sophia in three years is 150, then Sophia's age in three years will be 150 - 90 = 60. The answer is 60.
Question: Every 10 seconds, there is a car collision, and every 20 seconds there is a big crash. How many accidents overall will happen in 4 minutes?
