How I can fix this problem the word as an algebraic expression (no homework practice book.)?
I try to improve my math skills. Now I'm in algebra, but I can not translate word problems into algebraic expressions. Anyway, here's the problem: Two people take the path to another, two cities 100 miles away. If a person traveling at 30 miles per hour and one person traveling 20 miles per hour, how long it takes until they meet? * You do not need me to answer, just put the equation and explain what he did. Thanks
Let t (in hours) is the amount of time is for two people to meet:. Since distance = rate x time of the first person covers a distance of 30 miles * t = 30t. Similarly, the second person moves 20t miles. Since the initial difference between them is 100 km, these distances must be added the 100 miles. In other words, 30t + 20t = 100. I hope this help!
