Final answer:
It is estimated that a two-person crew will take approximately 20 minutes to collect recyclables from a 1000-foot-long street with homes 50 feet apart on both sides, assuming it takes 30 seconds to empty each container.
Step-by-step explanation:
To estimate the time it will take for a two-person crew to collect recyclables from green roll-out containers along a 1000-foot-long street, we can use basic math to calculate the number of stops and the total time required. If houses are 50 feet apart and they are on both sides of the street, we can determine the number of houses that will have recyclables to collect.
First, calculate the number of houses:
Number of houses = Total length of street / Distance between houses = 1000 feet / 50 feet = 20 houses on one side.
Since there are houses on both sides, we need to double this number:
Total number of houses = 20 houses * 2 = 40 houses.
Next, calculate the total collection time:
Time to empty one container = 30 seconds.
Total time = Time to empty one container * Total number of houses = 30 seconds * 40 houses = 1200 seconds.
To convert this into minutes, we divide by 60 (the number of seconds in a minute):
Total time in minutes = 1200 seconds / 60 = 20 minutes.
Therefore, it will take approximately 20 minutes for the crew to collect recyclables from the entire street.
