How Many Miles Is It From The Cable Bridge to The Blue Bridge and Back?

Here's a word problem for you. You thought you were done with those the last time you stepped out of your last math class in college, didn't you? Well try this one: how many miles is it from the cable bridge to the blue bridge, then across the blue bridge to Pasco, from the Pasco side back to the cable bridge, and then from there back over to Kennewick? This path would make a square. If you want bonus points, figure out how long it would take while walking, riding your bike, and/or rollerblading. Have fun calculating that and get out and enjoy this gorgeous weather we're having!
