We can set it up like this:
This states that Sam can drive 192 miles in 4 hours and 2220 miles in x hours. To solve, we can use cross-multiplication:
It will take Sam 46.25 hours to drive the whole trip, or 46 hours and 15 minutes.
Answer:
He is incorrect in this statement because 38 and 40 both have factors, other than 1 x itself. Prime numbers are numbers the only have 1 factor pair, and that is 1 x itself. Factors are the numbers you multiply to get the end result, and an example is 10x4=40. The factors of 40 are 8x5, 4x10, 2x20, and of course, 1x40. The factors of 38 are 2x19, and 1x38.
