The wheels on Noah's bike have a circumference of about 5 feet.
1. how far does the bike travel as the wheel makes the 15 complete rotations.
2. how many times do the wheels rotate if Noah rides 40 feet?
1. To find the distance the bike travels as the wheel makes 15 complete rotations, we need to multiply the circumference of the wheel by the number of rotations.
Distance = Circumference × Number of rotations
Distance = 5 feet × 15 rotations
Distance = 75 feet
Therefore, the bike travels 75 feet as the wheel makes 15 complete rotations.
2. To find the number of rotations the wheels make if Noah rides 40 feet, we need to divide the distance traveled by the circumference of the wheel.
Number of rotations = Distance ÷ Circumference
Number of rotations = 40 feet ÷ 5 feet
Number of rotations = 8 rotations
Therefore, the wheels rotate 8 times if Noah rides 40 feet.
