Question

Wheel of diameter 140cm moving with 66km/hr speed. Then distance travelled in one minute is

Answer 1

The thing is that we can’t help to help each other

Answer 2

Circumference of the wheel

= πd

= 22/7 × 140 cm

= 22×20cm

= 440 cm

so wheel cover 440 cm in one revelution

if it at speed of 66km/h then distance covered in one hour = (66 x 1000 x100) / 60 = 110000 cm

so ,

1 : ? :: 440cm : 110000cm

1×110000/440 = ?

250 = ?

so

a) 250 is right
