Question

the circumference of the front wheel of a car is 10 decimeter and that of the Hind wheel is 16 decimeter. how many Revolution more will the first wheel make than the second in covering a distance of 96 km?

Answer 1

10 decimeter = 1m
96 km = 96000m
revolution =
$\frac{96000}{1} \\ 96000$
wheel one will take 96000 revolutions.
16 decimeter = 1.6 m
96 km = 96000 m
revolution
$\frac{96000}{1.6} \\ 60000$
difference = wheel 1 revolution - wheel 2 revolution
96000 - 60000
= 36000
Therefore, the difference between two wheels is 36000
