Question

Ben can type 153 words in 3 minutes. at this rate, how many words can he type in 10 minutes?

Answer 1

Answer:

Ben can type 510 words in 10 minutes.

Step-by-step explanation:

The relation between the number of words typed and the minutes is direcltly proportional, that is, with Ben type more minutes, he will end up typing more words.

Thus, we can use the rule of three:

words    |    minutes

 153      ---      3

    x       ---      10

 

Now, we can just cross multiply them:

$153~ x~10 = x~ times~3$

$1530 = 3x\\3x= 1530\\x=\frac{1530}{3} \\= 510$

Thus, Ben can type 510 words in 10 minutes.

Answer 2

Answer:

Ben can type 510 words in 10 min.

Solution:

153/3=51 words per min

51*10 min= 510 words per 10 min
