Q: On a weekend road trip, the Jensen family drove 210 miles on highways, where their car gets 35 miles for each gallon of gas and 54 miles on city streets where their car gets 18 miles for each gallon. How many gallons of gas did they use?
A: On highways, the Jensen family used 210 miles / 35 miles / gallon = 6 gallons of gas. On city streets, the Jensen family used 54 miles / 18 miles / gallon = 3 gallons of gas. Total, the Jensen family used 6 gallons + 3 gallons = 9 gallons of gas. The answer is 9.
Question: A boy runs 1.5 km in 45 minutes. What is his speed in kilometers per hour?
Answer: Since 1 hour is equal to 60 minutes, then 45 minutes is equal to 45 / 60 = 0.75 hours. Then, the speed in kilometers per hour is 1.5 km / 0.75 hour = 2 kilometers per hour. The answer is 2.
[Question]Ali, Nada, and John have a total of $67 in their wallets. Ali has $5 less than Nada and John has 4 times more than Nada. How much money does John have?
[Answer]Let's say that N is what Nada has, J is what John has, and A is what Ali has. We know that A = N - 5 and J = 4N. We also know that: N + A + J = $67. We can substitute the equations from step 1 into the equations from step 2 to get: N + 4N + (N - 5) = $67. Combining like terms gets us 6N - 5 = $67. So, N = ($67 + 5) / 6 = $12. Substituting $12 back into the equation J = 4 N, we find John has 4 x 12 = $48. The answer is 48.
Q: Angie bought 3 lbs. of coffee at the store today. Each lb. of coffee will brew about 40 cups of coffee. Angie drinks 3 cups of coffee every day. How many days will this coffee last her?
A: A pound of coffee makes 40 cups of coffee, so 3 lbs. coffee * 40 cups of coffee per lb. = 120 cups of coffee. Angie drinks 3 cups of coffee a day, so she has enough coffee to last her 120 cups of coffee / 3 cups of coffee per day = 40 days. The answer is 40.
Question: John decides to get a new phone number and it ends up being a recycled number. He used to get 20 text messages a day. Now he is getting 55. Assuming the number of texts his friends send has not changed, how many text messages per week is he getting that are not intended for him?
Answer:
He is getting an extra 55 - 20 = 35 text messages per day. So he is getting an extra 35 * 7 = 245 text messages per week. The answer is 245.
