Q: James supercharges his car which increases his car's speed by 30%. He then cuts weight by 15% which increases the speed a further 10 mph. If his car's original speed was 150 mph what is the new speed?
A: He increased his speed by 150 * .3 = 45 mph. So his new speed was 150 + 45 = 195 mph. He increased it a further 10 mph so his new speed is 195 + 10 = 205 mph. The answer is 205.
Question: A class is 40% boys. The rest are girls. Every boy in class gets an 80% on the math test. Every girl gets a 90%. What is the class average on the test?

Q: Nina loves to travel. She tries to travel at least 400 kilometers in one month outside of her home country. Every second month she does twice that distance. If she were able to keep up with her resolution, how many kilometers would she travel during 2 years?
A:
Every second month Nina does twice the regular distance, which means 400 * 2 = 800 kilometers. Two years is 24 months, so half of this time is 24 * 0.5 = 12 months. So in 12 months Nina does 400 * 12 = 4800 kilometers. And in the other 12 months, she does 800 * 12 = 9600 kilometers. So in two years, Nina would be able to make 4800 + 9600 = 14400 kilometers. The answer is 14400.
