Logical Tire Use
Bill rode his bicycle 300 miles. Three tires were used equally in accumulating this distance. How many miles of wear did each tire sustain?
Sorry I didn't post on Friday. Blogger was being blocked at work and I couldn't get through!
I actually just wrote out an explanation for why I thought the answer was 100 miles each, but I erased it after I realized that was wrong. It's actually 200 miles each.
200 miles is the answer. Since the car travels 300 miles, the tires accrue 600 miles of wear in total. Divide that by 3 and you get 200 miles of wire on each tire.
Leave your answer or, if you want to post a question of your own, send me an e-mail. Look in the about section to find my e-mail address. If it's new, I'll post it soon.
Please don't leave spam or 'Awesome blog, come visit mine' messages. I'll delete them soon after.
