Question

Part C: Peru and The Machu Picchu Canal

Solve the following math questions about the Machu Picchu Canal.
1. Machu Picchu used to get about 72 inches of rainfall each year. How many
inches is that per month?
2. The canal carried about 80 gallons of water per minute from the spring. How
many gallons would the canal carry in 10 minutes?

Answer 1

1. 1 year = 12 months

that means there is 72 inches of rainfall every 12 months. 72/12 = 6 inches per month

2. 80 gallons per minute means you just have to multiply 80 by 10. 80 x 10 = 800 gallons in 10 minutes
