if Dm = decimeter ;
1. circumference 10 Dm = 1 meter
so revolution distance = 96000 meter .
so front wheel takes 96000 revolution.
2. similarly 1dm = 1/ 10 meter
so
16 Dm = 16/ 10 = 1.6 meter of circumference .
Rear wheel revolution = 96000/ 1.6 = 60000
so answer is 96000-60000= 36000
more revoption by front or first wheel
