Diameter of a wheel is $3 m$ The wheel revolves $28$ times in a minute To cover the distance of $5.280$ km the wheel will take $(π = \frac{2 2}{7})$

Question

Answer 1

Perimeter of the wheel $= 2 π r = 2 \times \frac{2 2}{7} \times 1.5 m$
$= \frac{6 6}{7} m$

Wheel covers a distance of $\frac{6 6}{7} \times 28 = 264 m$ in one minute

$∴$ it covers a distance of 5280 m in $= \frac{5 2 8 0}{2 6 4} = 20$ Minutes

Answer 2

Perimeter of the wheel

= 2 π r = 2 \times \frac{2 2}{7} \times 1.5 m

= \frac{6 6}{7} m

Wheel covers a distance of

\frac{6 6}{7} \times 28 = 264 m

in one minute

∴

it covers a distance of 5280 m in

= \frac{5 2 8 0}{2 6 4} = 20
