Jenna works in an ice cream shop. When she starts her shift, the tub of chocolate ice cream is 2/3 full. When she finishes her 6 1/2 hour shift, there is only 1/6 of the tub left. What was the average hourly change in tub fullness?

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.

its a straight line parallel to the time axis
