Sagot :

Answer:

  • Travel distance in one minute is 6028.8 inches or 502.4 feet or 167.5 yards

=======================

Given

  • Tire has radius of 12 in;
  • Tire does 80 revolutions per minute.

To find

  • Travel distance in one minute

Solution

Use circumference formula to find the tire circumference:

  • C = 2πr
  • C = 2*3.14*12 = 75.36 in

Find the distance by multiplying the number of revolutions by circumference:

  • d = 80*75.36 in = 6028.8 in

Convert the inches to feet, or yards, considering 12 in = 1 foot and 3 feet = 1 yard:

  • 6028.8/12 = 502.4 feet
  • 502.4 /3 = 167.5 yards
