on Tuesday, elena completed 20 of her math homework in 36 minutes. At that same rate, how long will it take her to complete 35 items for wendy's math home work
Let's use a proportion.
20/36 = 35/x
Cross multiply and solve for x.
20x = 1260
x = 63 minutes = 1 hour and 3 minutes
Ya... I could really use the answers to the whole test right about now...
I need all the answers
ps i liked my own comment
