Atanker truck fills the gas stations reservoir at the rate of 12 1/2 gallons per minute. if the reservoir was empty, and it is now 35 gallons full, how long has the tank been filling the reservoir?

2.8 minutes or 2 minutes and 48 seconds.

Step-by-step explanation:

A tanker truck fills the gas stations reservoir at the rate of gallons per minute.

∵ in 1 minute tanker truck fills the gas = gallons

                                                              = gallons

∴ to fill 35 gallons it will take time =

                                                        =

                                                        =

                                                        =

                                                        = minutes

                                                        = 2.8 minutes

                                                    or 2 minutes (0.8 × 60) 48 seconds

It will take 2.8 minutes or 2 minutes and 48 seconds to fill 35 gallons full.
