Answer 1

diameter of the bus wheel is 140cm

radius of the bus wheel is 70cm

circumference of the bus wheel

$2\pi \: r = 2 \times \frac{22}{7} \times 70 \\ 2 \times 22 \times 10 = 440$

$440 \: cm \\ or \: \frac{440}{10} \: m = 44m \\ or \frac{44}{1000} km = 0.044 \: km$

distance/speed=time

$\frac{66}{0.044} = \frac{66}{44} \times 1000 \\ \frac{3}{2} \times 1000 = 1500$
