Question

Savannah and Sarah are planning on riding their bikes to a point located at 1100 ft from their house their bicycle tires have a diameter of 26 in how many revolutions will their tires make on the path from their house to the park

Answer 1

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) = $2 \pi r = 2 \pi (13) = 81.68$

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
