Question

Each wheel of bicycle has a radius of 70 cm. how many complete revolutions does each wheel make to cover a distance of 2 km 520 m solution

Answer 1

total distance is equal to 2 km 520 m = 252000 cm and radius of wheel is 70 cm so circumference of wheel = 2×22÷7×70 cm= 440 cm

so,complete revolution should be252000÷440= 572 complete revolutions

Answer 2

total distance is equal to 2 km 520 m = 252000 cm ..............,..........................

*radius of wheel is 70 cm*

so circumference of wheel

= 2×22÷7×70 cm= 440 cm.....................

so,complete revolution should be

252000÷440

{∆572 complete revolutions∆}
