Challenge Problems
Push your limits with challenges.
Question 1
A site requires trucks to dump wet sand, which is known to be denser. If the gravimetric capacity of a truck is 15 tons, and each load weights 10 tons, how would you calculate the efficient dumping time considering the congestion from multiple trucks waiting to unload?
💡 Hint: Think of how one truck's delay can snowball as others line up to dump.
Question 2
Given two types of dump trucks where the bottom dump truck leads the unloading process with a time of 3 minutes and the rear dump takes 5 minutes, if you have 10 loads to dump under favorable conditions, calculate the efficiency ratio between the two.
💡 Hint: Efficiency is all about how fast you can complete the tasks at hand!
