To calculate the number of hours it will take for the company to build 39,000 cell phones, we need to use the given information that it takes 4 hours to build 1,300 cell phones.
First, let's calculate how many cell phones are built per hour. We can divide the number of cell phones (1,300) by the number of hours it takes to build them (4):
1,300 cell phones / 4 hours = 325 cell phones per hour
Now, we can use this rate to calculate how many hours it will take to build 39,000 cell phones. We divide the desired number of cell phones (39,000) by the rate at which they are built per hour (325):
39,000 cell phones / 325 cell phones per hour = 120 hours
Therefore, it will take approximately 120 hours for the company to build 39,000 cell phones if they continue working at the same rate.
