Question

A paving company was hired to make a 4 mile section of the highway. They need 700 tons of concrete to complete the job. How many yards of highway do they need to repave

Answer 1

The answer would be 175

Answer 2

There are 3 feet in a yard and 5280 feet in a mile. By dividing 5280 by 3 you will get the number of yards in 1 mile. 5280/3 = 1760 yards in 1 mile. 
To get the answer to your question you need to multiply 1760 by 4 since you have 4 miles, not one. So 1760 x 4 = 7040 yards of highway that they need to pave.
