The boys walk their bikes so that each wheel makes one complete turn. About how much farther will Barry’s bike travel compared to Jed’s? Answer: Distance Barry’s bike travels when the wheel makes one complete turn = circumference of wheel = π*diameter = π*50 cm = 157.0796326794897 cm Distance Jed’s bike travels when the wheel makes one complete turn = circumference of wheel = π*diameter = π*30 cm = 94.2477796076938 cm About how much farther will Barry’s bike travel compared to Jed’s? Difference in Distance = Distance Barry’s bike travels - Distance Jed’s bike travels Difference in Distance = 157.0796326794897 cm - 94.2477796076938 cm Difference in Distance = 62.8318530717959 cm >>> The final answer is: 62.8 cm Thanks for writing.
