Answer:
580 circulars
Step-by-step explanation:
Formula: Number of circulars divide by Hours
435 circulars / 3 hours = x circulars / 4.5 hours
145 circulars / 1 hour = x circulars / 4 hours
(145 circulars / 1 hour) * 4 hours = x circulars
580 circulars = x circulars
x = 580 circulars, delivered in 4 hours
Hence, at this rate James will delivers 580 circulars in 4 hours.
