Question

the circumference of the front wheel 10 decimeter and that of the hind wheel 16 decimeters how may revolutions more then the first wheel made than the second incovering a distance of 96 km.​

Answer 1

Answer:

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
