Solve the problem.A defendant in a collision case claims that he was traveling at 47 miles per hour (which happens to be under the speed limit) around a blind curve and did not have time to swerve to miss rear-ending the plaintiff, who had just pulled into the road. The investigating officer determines that any speed less than 60 feet per second would have allowed time to brake or swerve to avoid the collision. How would you judge the defendant?
A. Guilty. Because the defendant was only traveling 58 ft./sec., he should have had enough time to stop. B. Not guilty. Because the defendant was traveling 69 ft./sec., he did not have enough time to stop.
