100 Yard DashMath brain teasers require computations to solve.Bill and Ted race each other in a 100 yard dash. Bill wins by 10 yards. They decide to race again, but to make things fair Bill starts 10 yards behind Ted. If they both run exactly the same speed as before, who wins the race?
AnswerBill will win again. In the first race Bill ran 100 yards in the time it took Ted to run 90. Therefore in the second race, once Ted has run 90 yards they will both be side by side. Since Bill runs faster, he will take less time to run the last 10 yards than Ted and will therefore win.Hide What Next?
