Question

Cathy can text message about 52 words per minute. If she types at this rate for 20 minutes, about how many words will she type?

Answer 1

From the statement we know that Cathy can text messages at the following speed:

`s=52(w)/(\min )`

where, w = words, and min = minutes.

Now, if Cathy types at this rate for a time t = 20 min, she will type:

`s\cdot t=52(w)/(\min)\cdot20\min =1040w`

Answer: Cathy will type 1040 words.
