On a field trip kayla's school bus travels 120 miles in 3 hours. how far did it go in 2 hours? a) 40 miles b) 60 miles c) 80 miles d) 160 miles

The correct answer is option C) 80.

Step-by-step explanation:

We must start by analyzing the information we have.

We know that the school bus travels 120 miles in 3 hours.

Now we must find out how many miles he traveled in 2 hours.

Having 3 of 4 incognitas, the most convenient thing is to do a cross-multiplication.

So:  

if    3 hours 120 miles

       2 hours x miles

3.x = 120 .2

Now we just have to solve the equation:

3x = 120.2

3x = 240

x = 240: 3

x = 80

In this way we can verify that the correct answer is option C.

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.

my answer is$ 12

step-by-step explanation:

because 15 -2=12
