Find 3 consecutive integers whose sum is 171?

56,57,58

Step-by-step explanation:

a+(a+1)+(a+2)=171

3a+3=171

3a=171-3

3a=168

a=56

So the numbers are: 56, 57, 58.

Check: 56+57+58=171

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.
