Q: Jessica just got her driving permit. She must complete 50 hours of driving with a parent to get her driver's license. It takes 20 minutes to drive to school. If she drives to and from school every day, how many school days will it take Jessica to meet the 50-hour driving requirement?
A: Jessica will drive 20 minutes, twice every school day (to and from school), so 20 minutes x 2 trips = 40 minutes each day. There are 60 minutes in 1 hour, so 50 hours of driving x 60 minutes / hour = 3,000 minutes. If you take the 3,000 minutes she needs to drive / 40 minutes driving each day = 75 school days to drive 50 hours. The answer is 75.
Question: A bag full of sugar weighs 16 kg. A bag full of salt weighs 30 kg. If you remove 4 kg from the combined weight of these two bags, how much do the bags now weigh?

[Question]Val cuts a single watermelon into 40 slices, and each slice has 20 black seeds and 20 white seeds. What is the total number of seeds in a watermelon?
[Answer]40 slices per watermelon and each slice having 20 black seeds means each watermelon has 20 * 40 = 800 black seeds. 40 slices per watermelon and each slice having 20 white seeds means each watermelon has 20 * 40 = 800 white seeds. In total, each watermelon has 800 + 800 = 1600 seeds. What is the total number of seeds in a watermelon?. The answer is 1600.
Q: A family has three adults and children, both girls and boys. They went out for a family trip and prepared 3 dozen boiled eggs for the trip. Every adult got 3 eggs, and the boys each received 1 more egg than each girl since the girls had some snacks. How many boys went on the trip if the number of girls was 7 and each girl received an egg?
A: The total number of eggs the family had is 3 * 12 = 36 eggs. If each adult received 3 eggs, the total number of eggs they got is 3 * 3 = 9 eggs. The children shared 36 - 9 = 27 eggs. Since each girl received an egg, the boys shared 27 - 7 = 20 eggs. If each boy received 1 egg more than each girl, each received 1 + 1 = 2 eggs. The boys received 20 eggs, and if each got 2 eggs, then 20 / 2 = 10 boys went on the trip. The answer is 10.
Question: A chocolate bar weighs 125 g. A shopkeeper has just received a 2 kilogram box of chocolate. How many bars does this represent?
