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.
