Explanation:

Distance between A and B = (35 × 2) + (45 × 2) = 160 km.
Distance covered by Aditi in each speed segment $=\frac{160}{3}$
Hence, total petrol consumed

$=\left(\frac{160}{3}\times \frac{1}{16}\right)+\left(\frac{160}{3}\times \frac{1}{24}\right)+\left(\frac{160}{3}\times \frac{1}{16}\right)=8.9 l$
