Ben can type 153 words in 3 min. At this rate, how many words can he tyoe in 10 mins?
To find out how many words Ben can type in 10 minutes, we can set up a proportion:
3 minutes corresponds to 153 words.
10 minutes corresponds to x words.
Therefore, we can write the proportion as:
3/153 = 10/x
To solve for x, we can cross multiply:
3x = 153 * 10
Simplifying the right side of the equation gives:
3x = 1530
Dividing both sides of the equation by 3 gives:
x = 1530 / 3
Simplifying the right side of the equation gives:
x = 510
Therefore, Ben can type 510 words in 10 minutes.
