A wheel on Deon\'s bicycle is 0.7 m in diameter. Deon races the bicycle for 87 m. How many times does the wheel turn as the bicycle travels this distance? Use the value 3.14 for pi. Round your answer to the nearest tenth. Do not round any intermediate steps.

Solution

Linear distance = 87 mt

distance travelled by wheel in 1 turn = 2pi*radius = 2pi*(0.7/2) = 2.198 mt

No. of times wheel turn = linear distance/ distance travelled in 1 turn

= 87/2.198

= 39.58

= 39.6 turns
