Question

A delivery man can deliver 91 packages in 2 hours. If he continues at this rate, how many packages can the delivery man deliver in 8 hours?

Answer 1

Answer: 364

==============================================

Work Shown:

(91 packages)/(2 hours) = (x packages)/(8 hours)

91/2 = x/8

91*8 = 2*x .... cross multiply

728 = 2x

2x = 728

x = 728/2 .... divide both sides by 2

x = 364

-----------------

Another approach:

If he delivers 91 packages in 2 hours, then his unit rate is 91/2 = 45.5 packages per hour. Multiply this by the 8 hours

8*45.5 = 364
