Distance covered in 1 revolution = circumference of wheel
{tex}= \pi d{/tex}
{tex}= \pi \times 1.26 \mathrm { m }{/tex}.
Distance covered in 500 revolutions = 500 × circumference of wheel
= 500 ×{tex} \pi d{/tex}
{tex}= 500 \times \pi \times 1.26{/tex}
{tex}= 500 \times \frac { 22 } { 7 } \times 1.26{/tex}
= 1980m
= 1.98 km (1000m = 1km)
Distance covered in 500 revolutions is 1.98 km.
