Question

A crew of highway workers paved 15 mile in 18 hour. If they work at the same rate, how much will they pave in one hour?

Answer 1

5/6 miles

If they can pave 15 miles in 18 hours, they will pave and 18 of the miles in an 18 of the time, as 1/18 is an eighteenth. This means they will pave 15/18 miles, which simplifies to 5/6 miles.
