A relatively complex surfacing operation requires developing a 20, cubic meter solid rock source (26, cubic meters in the road prism) to surface km of road including shooting and crushing rock, loading, transporting, and spreading rock as follows.

To open up rock source, use data from clearing and common excavation:The equation is shown plotted as the solid curve in figure 5 for a car moving at 60 km/h on a road for which the value of the constant \(K\) is \(4\times 10^{-6}\).If the car now speeds up to km/h, the value of \(F(f)\) in equation 6 is multiplied by a factor of 2 \(^{}\), and the curve shifts bodily upwards to a new conclude that when we drive faster the road does indeed Preston, Lancashire The 5th of December AD.
