1. A shipping company operates 10 container ships that can each carry 5000 containers on each journey between ports. They want to be able to load and unload 20,000 containers each week. Assume their ships always travel fully loaded. What is the longest average travel time between ports that allows them to meet their goal of 20,000 containers per week

2.5 weeks

Step-by-step explanation:

Data provided in the question:

Number of container ships operated by the company = 10

Number of containers carried by each container = 5000

Number of container to be unloaded = 20,000

A shipping company operates 10 container ships

Now,

Capacity of 10 container ships = 10 × 5000 containers = 50,000 containers

Time required to load and upload 50,000 containers

= 50,000 containers  ÷ 20,000 containers per week

= 2.5 weeks

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
