Andres is cross country skiing from Massachusetts to Vermont. His first 25 miles takes him 4 hours to complete. At this rate, how long will it take him to complete the entire 200 mile journey? a) write a proportion to represent the situation b) solve it!

a) We can write the proportion as:

25 miles / 4 hours = 200 miles / x hours

b) To solve the proportion, we can cross-multiply:

25 * x = 4 * 200

25x = 800

Divide both sides by 25:

x = 800 / 25

x = 32

So, it will take him 32 hours to complete the entire 200-mile journey.
