Solution

Given diameter of front, d1=80 cm

And diameter of rear wheels, d2=2m=200 cm

Radius of front wheel (r1)=802=40cm

And radius of rear wheel (r2)=2002=100cm

Circumference of the front wheel
=2πr1=2×227×40=17607

Total distance covered by front wheel
=1400×17607=200×1760

=352000 cm

Number of revolutions by rear wheel =Distance coveredCircumference

=3520002×227×100=7×35202×22=2464044=560
