Question

Diego can type 140 words in 4 minutes. At this rate, how long will it take him to type 385 words?

Answer 1

To calculate how long it will take Diego to type 385 words at a rate of 140 words in 4 minutes, you can set up a proportion:

(140 words / 4 minutes) = (385 words / x minutes)

Now, solve for x:

140/4 = 385/x

35 = 385/x

To isolate x, divide both sides by 35:

x = 385/35
x = 11

So, it will take Diego 11 minutes to type 385 words at his given rate.
