SOLUTION :-
★ Distance travelled in 1 min
==> {6 km÷1 hour}×(10 min)
==> {6 km÷ 60 min}×(10 min)
==> 1 km
==> (1×1000×100) cm
==> 1,00,000 cm
==> Circumference of wheel = (2×22×20) ÷7
==> (44 × 20 ÷ 7) cm
==> 968 ÷ 7
● Number of revolutions = (1,00,000) ÷(968÷7)
● Number of revolution = 1,00,000 × 7 ÷ 968
● Number of revolution = 723.14 approx 723 revolution
