Question: The average speed for an hour drive is 66 miles per hour. If Felix wanted to drive twice as fast for 4 hours, how many miles will he cover?
Answer with step-by-step thinking: If Felix drives twice as fast, he will be covering 2 * 66 = 132 miles per hour. In four hours, driving at 132 miles per hour, since distance = speed * time, Felix will cover 132 * 4 = 528 miles.
So the answer is 528.


Question: John has a party and invites 30 people. Of the people he invited 20% didn't show up. 75% of the people who show up get steak and the rest get chicken. How many people ordered chicken?
Answer with step-by-step thinking: There were 30 * .2 = 6 people who didn't show up. So 30 - 6 = 24 people showed up. Of the people who showed up, 24 * .75 = 18 got steak. So 24 - 18 = 6 got chicken.
So the answer is 6.


Question: At school today, Charlize was 20 minutes late. Four of her classmates were each ten minutes late than she was. What's the total time for which the five students were late?
Answer with step-by-step thinking:
If Charlize was 20 minutes late, each of her friends was 20 + 10 = 30 minutes late. The total time for which Charlize's friends were late was 4 * 30 = 120 minutes. Together with Charlize, the three friends were 120 + 20 = 140 minutes late.
So the answer is 140.
