Answer 2

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.
