We have a question: Mark is a lawyer who works at the county courthouse every day. It takes him 5 minutes to find parking and 3 minutes to walk into the courthouse. 2 days of the week it takes him 30 minutes to get through the metal detector and the other 3 days are less crowded so he gets through in 10 minutes. How long does he spend on all these activities in a week with 5 work days?
And an answer: 130
So how you got the answer?
First find how long Mark spends on parking and walking each day: 5 minutes + 3 minutes = 8 minutes. Then multiply that number by his number of workdays to find the total walking and parking time: 8 minutes / day * 5 days / week = 40 minutes / week. Then multiply the number of long - wait days by the time of each long wait: 2 days / week * 30 minutes / day = 60 minutes / week. Then multiply the number of short - wait days by the time of each short wait: 3 days / week * 10 minutes / day = 30 minutes / week. Then add the length of time Mark spends on each activity to find the total time spent: 30 minutes / week + 60 minutes / week + 40 minutes / week = 130 minutes / week.

We have a question: There is a pie-eating contest at school. Adam eats three more pies than Bill. Sierra eats twice as many pies as Bill. If Sierra ate 12 pies, how many pies were eaten in total?
And an answer: 27
So how you got the answer?
Bill ate 12 / 2 = 6 pies. Adam ate 6 + 3 = 9 pies. They ate a total of 6 + 9 + 12 = 27 pies.

We have a question: Jimmy is going to sell pizzas at the carnival to make some money. The carnival only gave him 7 hours to do so. He bought a 22kg sack of flour to make his pizzas and he takes 10 min to make each pizza for the customers. At the end of the 7 hours, he saw some flour was left. Knowing that each pizza needs 0.5kg of flour to make, how many pizzas can he make to bring home with the flour left?
And an answer: 2
So how you got the answer?
Each hour Jimmy makes 60min 10min / pizza = 6 Pizzas. The number of total pizzas made equals 7 hours x 6 pizzas / hour = 42 pizzas. The amount of total flour used equals 42 pizzas x 0.5 kg / pizza = 21 kg. The amount of flour left equals 22 kg - 21 kg = 1 kg. The number of pizzas Jimmy can make is 1kg 0.5kg / pizza = 2 pizzas.
