Answer 2

A tire b had to fill 2 1/2 tires with air. It took a small air compressor 2 1/2 seconds to fill them up.The time taken to fill 8 tires is 8 seconds

Step-by-step explanation:

Time taken by small air compressor to fill air in
`2 (1)/(2)` tires in a tire shop =
`2 (1)/(2)` seconds

So, time taken by the small air compressor to fill air in 1 tire

=
`2 (1)/(2)` divided by
`2 (1)/(2)`

=
`(2 (1)/(2) )/(2 (1)/(2))`

= 1 second

So, time taken by it to fill 8 tires = 8*1 seconds

= 8 seconds

which is the the time taken to fill 8 tires
