Atanker truck fills the gas station's reservoir at the rate of
12 gallons per minute. if the reservoir was empty and it is now
35 gallons full, how long has the tanker been filling the reservoir?

The time taken by tanker to fill the reservoir is 2.9 minutes

Step-by-step explanation:

Given as :

The rate at which tanker truck fill the reservoir = 12 gallons per minute

Total gallons which is filled in the reservoir = 35

Now ,

∵ To fill 12 gallons of reservoir , the time taken = 1 minute

So, To fill 1 gallons of reservoir , the time taken = minute

∴ To fill 35 gallons of reservoir , the time taken = × 35  min

i.e To fill 35 gallons of reservoir , the time taken = 2.9 minutes

Hence The time taken by tanker to fill the reservoir is 2.9 minutes Answer
