r = 63 cm
firstly find, circumference of wheel= 2πr
=2×22/7×63=396
then, convert the distance in cm= 1540 ×100
=154000cm
no. of turns of wheel = distance / circumference
= 154000/396
= 388 (app.)

radius of wheel in cm=63cm
radius of wheel in m=63/100=0.63m
circumference of wheel= 2×pi×radius
2×22/7×63/100
44×9/100
11×9/25
99/25m
Total distance=1540m
total turns to cover 1540m=1540/(99/25)
=38,500m/99
=388 turns(approx.)
HOPE IT HELPS YOU
