The diameter of each wheel of vehicles is 42cm. Each wgeel makes 20 revolutions in 12 seconds.Find the speed of the vehicle in metre per minute.

$\large { \underline{ \bf \purple{Solution:- }}}$

$\large { \underline{ \bf \pink{Given:- }}}$

• Diameter of Each vehicle is 42cm
• Each wheel makes 20 revolutions in 12 seconds.

$\large { \underline{ \bf \green{To\:find:- }}}$

• Find the speed of the vehicle in metre per minute.

$\large { \underline{ \bf{Let's\:do:- }}}$

Diameter (D)= 42cm

Circumference = (pie)D=

$( \frac{22}{7} ) \times D=( \frac{22}{7} ) \times 42 = 132cm</p><p>$

1 circumference = 1 revolution

1 revolution = 132cm = 1.32m

For covering 5.28km number of revolution =

$\frac{5.28 \times 100}{1.32} = 4000$

$\large { \underline{ \bf \orange{Therefore:- }}}$

• 4000 is the speed of the vehicle in metre per minute.
