Answer:
323.2 revolutions (324 revolutions (rounded) )
Step-by-step explanation:
Savannah has to cover 1100 feet
Sarah has to cover 1100 feet
Now,
For Savannah:
diameter is 26 in, so radius will be 26/2 = 13 inches
Circumference (1 rev) = [tex]2 \pi r = 2 \pi (13) = 81.68[/tex]
There are 12 inches in 1 feet, so distance to be covered in inches:
1100 * 12 = 13,200 inches
Number of revolutions = 13,200/81.68 = 161.6 revolutions
For Sarah, it is the same so:
161.6 revolutions
Together:
161.6 + 161.6 = 323.2 revolutions to cover the whole distance (both)
Rounded, it is About 324 revolutions
