Answer: 1000 rotations.
Step-by-step explanation:
The circumference of a circle= Distance travelled in one rotation.
Circumference= 2πr, where r= radius.
= 2×(22/7)×1.75= 11m= 0.011km
Distance travelled in 1 rotation= 0.011km
Distance travelled in 1000 rotations= 0.011×1000= 11km.
So, it takes 1000 rotations to travel 11km.
