Hallo! HELP!!! I have a problem… here it is!
Write the ratio as a unit rate.
286 miles in 5 1/2 hours.

ALSO I need a little help with dis too.
Which typing time is the fastest?
320 words in 8 minutes
600 words in 12 minutes
350 words in 10 minutes
225 words in 5 minutes

How do you solve this?
How do you check?
Some people say you divide. Why?
Answered by Writeacher
For your second question, yes, you divide to find the fastest typing time.
320 divided by 8
600 divided by 12
etc.

What about the first question?
Answered by Writeacher
A math tutor may correct me, but I think the first thing to do is get rid of the fraction and express that number in a decimal format. What does 5 1/2 equal in decimals?

I think you should find out a number that 5, 8, 10, and 12 have a multiple of like I think 60 and find out words in 60 minutes
