A machine stamps 360 metal parts in 45 minutes. Find the unit rate in parts per hour.

15 min 30 sec is actually 930 seconds

3600 sec in hour

-- not finished, working on it

Step-by-step explanation:

360/45 = x/60

45n = 60

n = 60/45

n = 1.333 or 1 and 1/3

multiply the numerator by the same amount as the denominator

360 multiplied by 1.333 = 480

480parts/hour
