Question: "I was walking along the road at three and a half miles an hour," said Mr. Pipkins, "when the car dashed past me and only missed me by a few inches." "Do you know at what speed it was going?" asked his friend. "Well, from the moment it passed me to its disappearance round a corner.
I took twenty-seven steps and walking on reached that corner with one hundred and thirty-five steps more." "Then, assuming that you walked, and the car ran, each at a uniform rate, we can easily work out the speed."
Answer: As the man can walk 27 steps while the car goes 162, the car is clearly going six times as fast as the man. The man walks 3 1/2 miles an hour: therefore the car was going at 21 miles an hour.
