It takes 5 minutes to read a passage that has 800 words with the same speed.
SOLUTION:
Given that, during a reading test, Enrique reads a passage with 640 words. It takes him 4 minutes to read the passage.
We have to find time taken by Enrique to read a passage that has 800 words if he reads at the same speed
Now, we know that,
[tex]640 \text { words } \rightarrow 4 \text { minutes }[/tex]
Then, [tex]800 \text { words } \rightarrow \text { (let it be) n minutes }[/tex]
So, by cross multiplication method
[tex]\Rightarrow n \times 640=4 \times 800 \rightarrow n \times 64=4 \times 80 \rightarrow n \times 16=80 \rightarrow n \times 2=10 \rightarrow n=5[/tex]
Cross multiplications steps: (To find Single Variable)
Step 1: Multiply the numerator of the left-hand fraction by the denominator of the right-hand fraction.
Step 2: Multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction.
Step 3: Set the two products equal to each other.
Step 4: Solve for the variable.
