Answer:
h=1.29 c=0.79
Step-by-step explanation:
We can work out the circumference of the wheel by using the equation
C = πd
C = π × 2
C = <span>6.28318530718
C = 6 feet
If 1km is 3280 feet, 2km is 6560 feet
6560 </span>÷ 6 = <span>1093.33333333 (recurring)
= 1093
Therefore the bike wheels rolls (approximately) 1093 times to cover 2km.
