The circumference of a circular track is 9 km9\text{ km}. A cyclist rides round it a number of times and stops after covering a distance of 302 km302\text{ km}. How far is the cyclist from the starting point (along the track)?

Worked solution (try it first)
  1. Each lap is 9 km.
  2. Divide 302 by 9: 9×33=2979 \times 33 = 297, with 302−297=5302 - 297 = 5 km left over.
  3. After 33 full laps the cyclist is back at the start, then rides 5 km more.
  4. So the cyclist is 5 km from the start, option A.
