GATE Civil Engineering (CE) 2018 Shift 2 Solved Paper

A car follows a slow moving truck (travelling at a speed of $10\mathit{m}/\mathit{s}$ ) on a two-lane two-way highway. The car reduces its speed to $10\mathit{m}\mathit{m}/\mathit{s}$ and follows the truck maintaining a distance of 16 $\mathit{m}$ from the truck. On finding a clear gap in the opposing traffic stream, the car accelerates at an average rate of $4\mathit{m}∕{\mathit{s}}^2$, overtakes the truck and returns to its original lane. When it returns to its original lane, the distance between the car and the truck is $16\mathit{m}.$ The total distance covered by the car during this period (from the time it leaves its lane and subsequently returns to its lane after overtaking) is
