Word problem:  Joe drives 20 miles in 1/2 hour.  How long will it take him to drive 50 miles?  I know the answer is 1 hour and 15 minutes. What is the equation I should write?

Sep 30th, 2014

problem

20miles= 30minutes

50miles=? minutes

cross multiply

(50miles*30minutes)/20miles

(50*30)/20 minutes

75 minutes or 1 hour and 15 minutes like you said
