Question

A crew of workers paved 3/15 of mile in 20 minutes. If they work at the same rate, how much of a mile will they pave in 1 hour

Answer 1

9/15 of a mile or 3/5 of a mile

explanation: since there are 3 sets of 20 minutes now an hour and they can pave 3/15 of a mile in an hour, you multiply the 20 minutes times 3 to get one hour, then multiply the numerator of 3/15 times 3 to get 9/15. then you simply. hope this helped :)
