Jim spends 30 minutes writing 10 sentences (slowpoke!). If he has 30 more sentences to write and continues writing at this same rate, how long should it take him to finish the entire assignment? (I know the answer it's just that I want to see if anyone is going to reply...probably not)

Answer:

90 minutes

Step-by-step explanation:

If Jim takes 30 minutes to write 10 sentences, we can write a proportion.

[tex]\frac{30}{10}=\frac{x}{30}[/tex]

Cross multiply so we get [tex]10x=900[/tex].

And simplify.

[tex]x=90[/tex]
