Answer:

1,031 revs.

Explanation:

Using angular motion equation,

s = 2π*r*n

Where,

s = length or distance covered

r = radius of the circle

n = number of turns/revolutions

2πrn1 = 2πrn2

Therefore,

r2n2 = r1n1

r2n2 = r1n1

n2 = r1n1 / r2

n2 = (1.20 * 292) / 0.340

= 1,030.588 revs

= 1,031 revs.
