Question: Jorge has an equal number of baseball cards as Matias, who has 6 fewer cards than Carlos. If Carlos has 20 baseball cards, what is the total number of baseball cards the three have?
Answer with step-by-step thinking: If Carlos has 20 cards, Matias has 20 - 6 = 14 baseball cards. Since Matias and Jorge have the same amount of baseball cards, the total number of cards the three have is 14 + 14 + 20 = 48 cards.
So the answer is 48.


Question: James buys twice as many toy soldiers as toy cars. He buys 20 toy cars. How many total toys does he buy?

So the answer is 60.


Question: Apple can run at a rate of 3 miles per hour. Mac can run at a rate of 4 miles per hour. In minutes, how much faster will Mac run a 24 mile race?
Answer with step-by-step thinking:
First find how fast each runs. Apple = 24 miles / 3 miles per hour = 8 hours. Mac = 24 miles / 4 miles per hour = 6 hours. Mac runs 8 hours - 6 hours = 2 hours faster. 1 hour = 60 minutes, so, Mac runs faster by 2 hours * 60 minutes = 120 minutes.
So the answer is 120.
