Answer:

2.8 minutes or 2 minutes and 48 seconds.

Explanation:

A tanker truck fills the gas stations reservoir at the rate of
12(1)/(2) gallons per minute.

∵ in 1 minute tanker truck fills the gas =
12(1)/(2) gallons

=
(25)/(2) gallons

∴ to fill 35 gallons it will take time =
(35)/((25)/(2))

=
(35* 2)/(25)

=
(70)/(25)

=
(14)/(5)

=
2(4)/(5) 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.
