Answer 2

Heya user !!

Here's the answer you are looking for

The circumference of the wheel is 1.5m, that means it covers 1.5m after one complete rotation of the wheel

3km = 3000m

If it covers 1.5 m in 1 rotation,

Then, it will cover 3000m in
$\frac{1}{1.5} \times 3000 \\ = 2000$
(By unitary method)

Therefore, it will cover 3km with 2000 rotations.
