<span>if it is travelling 20 feet in 1/5 of a second that means that in 1 second (which is 5 times as much as 1/5 of a second) it will do 5 times 20 feet hence 100 feet. Then in 3 seconds it will do 300 feet</span>
20.2 is the perfect answer
well, Marcus and Ben are both 5 feet tall and a little bit more, Marcus is 19/24 more and Ben is 9/16 more, so the 5's in the fraction are the same, so which one is larger, 19/24 or 9/16?
we can simply put both fractions with the same denominator, by <u>multiplying one by the other's denominator</u>, so let's proceed,

C is the answer for this question
we are supposed to find
The expression that completes the statement to form a true inequality

Here 
So the given inequality to be true the value of the option(s) should me bore than 39
First option: 
As its not more than 39. Hence its not the correct option.
Second Option : 
Hence this is the correct option so,

Third Option: 
As its not more than 39. Hence its not the correct option.
Fourth Option: 
As its not more than 39. Hence its not the correct option.
