The Chang family is on their way home from a

cross-country road trip.

During the trip, the

function

D(t) = 2,280 - 60t can be

used to model their

distance, in miles, from

home after t hours of

driving.

Find D(15) and interpret

the meaning in the context

of the probieu.

If DC) = 1,200, find the

value of ĉ and interpret its

meaning in the context of

the problem.

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.
