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

Answers

Answer:

In 10 minutes, he could type 510 words

Step-by-step explanation:

153/3=51 51 words a minute   51 times 10=510

Answer:

510 words

Step-by-step explanation:

This is how I would solve this problem:

153 words = 3 minutes

153/3 = 3/3

51 words per minute

To find the number of words Ben can tye in 10 minutes, we need to multiply the unit rate (51:1) by 10. Like so:

51 words * 10 = 1 minute * 10

510 words = 10 minutes

This means that Ben can types 510 words in 10 minutes.
