Question

4. The wheele of a car are of diameter 80 cm each. How many complete revo
each wheel make in 10 minutes when the car is travelling at a speed of 66 km
${ { { { { { { { { { { { { { \\ \\ \\ \\ \\ }^{?} }^{?} }^{?} }^{?} }^{?} }^{?} }^{?} }^{?} }^{?} }^{?} }^{?} }^{?} }^{?} }^{?}$
​

Answer 1

Answer:

distance covered by car in 10min = 110,000 x 10 = 11,00,000cm. distance covered in 10min / distance covered in one revolution. = 11,00,000/1 x 7/1760 = 4375 revolutions. Hence, in 10min each wheel of car makes 4375 revolution

Answer 2

Answer:

distance covered by car in 10min = 110,000 x 10 = 11,00,000cm. distance covered in 10min / distance covered in one revolution. = 11,00,000/1 x 7/1760 = 4375 revolutions. Hence, in 10min each wheel of car makes 4375 revolutions
