Ann and John go to a swimming pool. They both swim the first length of the pool in 2 minutes. The time John takes to swim a length is 6 seconds more than he took to swim the previous length. The time Ann takes to swim a length is 1.05 times that she took to swim the previous length.
Find the time it takes each of them to swim their 20th length.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
