Solve the problem.A defendant in a collision case claims that he was traveling at 36 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. Not guilty. Because the defendant was traveling 64 ft./sec., he did not have enough time to stop. B. Guilty. Because the defendant was traveling only 53 ft./sec., he should have had enough time to stop.
