<human>:  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?
<bot>: How many kilometers does Nina travel every second month? ** Every second month Nina does twice the regular distance, which means 400 * 2 = <<400*2=800>>800 kilometers.
How many months are in two years? ** Two years is 24 months, so half of this time is 24 * 0.5 = <<24*0.5=12>>12 months.
How many kilometers does Nina travel in 12 months? ** So in 12 months Nina does 400 * 12 = <<400*12=4800>>4800 kilometers.
How many kilometers does Nina travel in the other 12 months? ** And in the other 12 months, she does 800 * 12 = <<800*12=9600>>9600 kilometers.
How many kilometers would Nina travel in two years? ** So in two years, Nina would be able to make 4800 + 9600 = <<4800+9600=14400>>14400 kilometers.
