First, you want to be sure
you understand the question and what answer
you are going to look for in this problem. You are
being asked to find out how far a meteroid travels
in 60 seconds, knowing that they travel 19 kilometers
per second.
To find the solution or answer to the question
you would multiply 19 kilometers times 60 seconds
to find how far the meteroid travels in 60 seconds.
Notice that as you reread the problem, the line "It
becomes visible from the earth when it is 96
kilometers above the ground" has nothing
to do with finding the answer to the question
you were asked. Therefore, the extraneous information
in this problem is the sentence, "It
becomes visible from the earth when it is 96
kilometers
above the ground." |
