Question

You have been cleaning diesel dispensers for 35 minutes. You have completed 6 dispensers. How many minutes has it taken you to clean 1 dispenser?* 6.83 5.22 5.83

Answer 1

35 minutes for all 6 dispensers. To get the number of minutes per dispenser, simply divide the total number of minutes by the number of dispensers cleaned.

35 minutes / 6 dispensers = 5.83 minutes per dispenser.

With that rate, we can conclude that the change in the number of dispensers cleaned will result to the variation of the total number of minutes spent cleaning the dispensers.

y = 5.83x

where y is the total number of minutes spent cleaning the x number of dispensers. For example:

y = 5.83 * 6 dispensers
y = 34.98 minutes or rounded off to 35 minutes.
