My math homework is confusing. Can you please answer these questions for me?
1. On a map, 1.25 inches represents 7 miles. If two cities are 7.5 inches apart on the map, find the actual distance they are apart.
2. The blueprints on a house have a scale of 1 in : 3 ft. If the length of a room on the blueprint is 17 inches, what would the measurement of the length of the room be?
3. Dave drives 200 miles in 2 days. How many miles could he drive in 7 days?
Please work these out as proportions and show all of the work, Thanks for any help!*

1.) 1.25:7, so 7.5:?. Here's how: (7.5 x 7) / (1.25) = 42 miles.

2.) 1:3, so 17:?. For this one: (17 x 3) / (1) = 51 feet.

3.) 200:2, so?:7. And finally: (200 x 7) / (2) = 700 miles.

See the pattern?
