Question:

(PHILLY)

Each wheel on Barry’s bike is 50 cm in diameter. Each wheel on Jed’s bike is 30 cm in
diameter. 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
