Amallard duck flies 5/6 of a mile in 1/60 of a hour. compute the unit rate by setting up a complex fraction and simplifying. a) 25 miles per hour b) 30 miles per hour c) 50 miles per hour d) 60 miles per hour

a) justify

step-by-step explanation:

justifying is just part of everyday life. justify kind of means proof so i think the answer is a) justify.

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.
