Question

A car is 70 cm in diameter of each wheel. If the speed of the car is 60 kmph, will each wheel complete the time in 10 minutes?

Answer 1

Answer:

Diameter = 70 cm

Circumference = \pi d=\frac{22}{7}\times70=220=\frac{220}{100}m

No. of revolutions in 1 km

= 1km\ \div\frac{220}{100}m

= 1\times1000\times\frac{100}{220}m=\frac{5000}{11}=454\ \frac{6}{11}km
