Answer 2

Answer:

250 rotations

Step-by-step explanation:

Circumference of the wheel

$= \pi d \\ = \frac{22}{7} \times 1.4 \\ = 4.4 \: m$

Required number of rotations

$= \frac{total \: distance}{circumference} \\ = \frac{1.1 \: km}{4.4 \: m} \\ = \frac{1.1 \times 1000 \: m}{4.4 \: m} \\ = 250$
