The Deep Dive
To tackle this problem, we first need to derive the relationship. Since time
varies directly as the number of vehicles
and inversely as the number of pumps
, we can express it as:
Where
is a constant. Given that it took 10 minutes to fuel 20 vehicles at a station with 5 pumps, we can substitute these values to find
:
Now we have:
To find the time it will take to fuel 50 vehicles at a station with 2 pumps, we substitute
and
:
So, it will take 62.5 minutes to fuel 50 vehicles with 2 pumps.
Did you know that in some countries, the number of vehicles at fuel stations can increase significantly during holiday seasons or major events, leading to longer waiting times? Knowing how to optimize the number of pumps and manage queues can significantly impact customer satisfaction.
Moreover, while calculating relationships like this, common mistakes include forgetting to correctly apply direct and inverse relationships or misplacing constants. Double-checking each step can prevent such errors and help you nail those math problems!
