After Lee Ann Spahr had pumped 5.0 gal of gasoline, the display showing the price read $16.60. When she finished pumping the gasoline, the price display read $48.14. How many gallons did she pump?
To solve this problem, set up a proportion, with prices in the numerators and gallons in the denominators. Let x = the number of gallons she pumped.
She pumped 14.5 gal. Check this answer. (Using a calculator reduces the possibility of error.) Notice that the way the proportion was set up uses the fact that the unit price is the same, no matter how many gallons are purchased.
The distance between Singapore and Tokyo is 3300 mi. On a certain wall map, this distance is represented by 11 in. The actual distance between Mexico City and Cairo is 7700 mi. How far apart are they on the same map?
